DESCRIPTION
The TPS2204A and TPS2206A PC CardBus
power-interface switches provide an integrated
power-management solution for two PC Card sockets.
The TPS2210A is a single-slot option for this family of
devices. These devices allow the controlled distribution of
3.3 V, 5 V, and 12 V to each card slot. The current-limiting
and thermal-protection features eliminate the need for
fuses. Current-limit reporting helps the user isolate a
system fault. The switch rDS(on) and current-limit values
are set for the peak and average current requirements
stated i n the PC Card specification, and are optimized for
cost.
The TPS2206A is pin and/or functionally compatible with
the TPS2206, TPS2216, TPS2216A, TPS2226,
TPS2226A, and TPS2228 with a few exceptions, as
shown in the Available Options table.

APPLICATION INFORMATION
OVERVIEW
PC Cards were initially introduced as a means to add flash memory to portable computers. The idea of add-in cards quickly
took hold, and modems, wireless LANs, global positioning satellite system (GPS), multimedia, and hard-disk versions were
soon available. As the number of PC Card applications grew, the engineering community quickly recognized the need for
a standard to ensure compatibility across platforms. To this end, the PCMCIA (Personal Computer Memory Card
International Association) was established, comprising members from leading computer, software, PC Card, and
semiconductor manufacturers. One key goal was to realize the plug-and-play concept, so that cards and hosts from
different vendors would be transparently compatible.
PC CARD POWER SPECIFICATION
System compatibility also means power compatibility. The most current set of specifications (PC Card Standard) set forth
by the PCMCIA committee states that power is to be transferred between the host and the card through eight of the 68
terminals of the PC Card connector. This power interface consists of two VCC, two Vpp, and four ground terminals. Multiple
VCC and ground terminals minimize connector-terminal and line resistance. The two Vpp terminals were originally specified
as separate signals, but are normally tied together in the host to form a single node to minimize voltage losses. Card primary
power is supplied through the VCC terminals; flash-memory programming and erase voltage are supplied through the Vpp
terminals.
DESIGNING FOR VOLTAGE REGULATION
The current PCMCIA specification for output voltage regulation, VO(reg), of the 5-V output is 5% (250 mV). In a typical PC
power-system design, the power supply has an output-voltage regulation, VPS(reg), of 2% (100 mV). Also, a voltage drop
from the power supply to the PC Card results from resistive losses, VPCB, in the PCB traces and the PCMCIA connector.
A typical design would limit the total of these resistive losses to less than 1% (50 mV) of the output voltage. Therefore, the
allowable voltage drop, VDS, for the device would be the PCMCIA voltage regulation less the power supply regulation and
less the PCB and connector resistive drops:
VDS +VO(reg)–VPS(reg)–VPCB
Typically, this would leave 100 mV for the allowable voltage drop across the TPS2204A, TPS2206A, or TPS2210A. The
voltage drop is the output current multiplied by the switch resistance of the device. Therefore, the maximum output current,
IO max, that can be delivered to the PC Card in regulation is the allowable voltage drop across the device, divided by the
output-switch resistance.
IOmax +VDS
rDS(on)
The xVCC outputs have been designed to deliver the peak and average currents defined by the PC Card specification
within regulation over the operating temperature range. The xVPP outputs have been designed to deliver 100 mA
continuously.

OVERCURRENT AND OVERTEMPERATURE PROTECTION
PC Cards are inherently subject to damage that can result from mishandling. Host systems require protection against
short-circuited cards that could lead to power-supply or PCB trace damage. Even extremely robust systems could undergo
rapid battery discharge into a damaged PC Card, resulting in the rather sudden and unacceptable loss of system power.
The reliability of fused systems is poor, in comparison, as blown fuses require troubleshooting and repair, usually by the
manufacturer.
The TPS2204A, TPS2206A, and TPS2210A take a two-pronged approach to overcurrent protection. Overcurrent
protection is designed to activate if an output is shorted or when an overcurrent condition is present when switches are
powered up. First, instead of fuses, sense FETs monitor each of the xVCC and xVPP power outputs. Unlike sense resistors
or polyfuses, these FETs do not add to the series resistance of the switch; therefore voltage and power losses are reduced.
Overcurrent sensing is applied to each output separately. Excessive current generates an error signal that limits the output
current of only the affected output, preventing damage to the host. Each xVCC output overcurrent limits from 1 A to 2.2
A, typically around 1.6 A; the xVPP outputs limit from 100 mA to 250 mA, typically around 200 mA.
Second, when an overcurrent condition is detected, the device asserts an active low OC signal that can be monitored by
the microprocessor or controller to initiate diagnostics and/or send the user a warning message. If an overcurrent condition
persists, causing the IC to exceed its maximum junction temperature, thermal-protection circuitry activates, shutting down
all power outputs until the device cools to within a safe operating region, which is ensured by a thermal shutdown hysteresis.
Thermal limiting prevents destruction of the IC from overheating beyond the package power-dissipation ratings.
During power up, the devices control the rise times of the xVCC and xVPP outputs and limit the inrush current into a large
load capacitance, faulty card, or connector.
12-V SUPPLY NOT REQUIRED
Some PC Card switches use the externally supplied 12 V to power gate drive and other chip functions, which requires that
power be present at all times. The TPS2204A, TPS2206A, and TPS2210A offer considerable power savings by using an
internal charge pump to generate the required higher gate drive voltages from the 3.3-V input. Therefore, the external 12-V
supply can be disabled except when needed by the PC Card in the slot, thereby extending battery lifetime. A special feature
in the 12-V circuitry actually helps to reduce the supply current demanded from the 3.3-V input. When 12 V is supplied and
requested at the Vpp output, a voltage selection circuit draws the charge-pump drive current for the 12-V FETs from the
12-V input. This selection is automatic and effectively reduces demand fluctuations on the normal 3.3-V VCC rail. For proper
operation of this feature, a minimum 3.3-V input capacitance of 4.7 µF is recommended, and a minimum 12-V input ramp-up
rate of 12 V/50 ms (240 V/s) is required. Additional power savings are realized during a software shutdown in which
quiescent current drops to a maximum of 1 µA.
BACKWARD COMPATIBILITY
The TPS2206A is backward compatible with the TPS2206 product, with the following considerations. An active low /SHDN
is added to provide fast shutdown capability. Also, the TPS2206A does not have the active−high RESET input, which is left
as no connect.
3.3–V input is required for device operation of TPS2206A.
VOLTAGE-TRANSITIONING REQUIREMENT
PC Cards, like portables, are migrating from 5 V to 3.3 V to minimize power consumption, optimize board space, and
increase logic speeds. The TPS2204A, TPS2206A, and TPS2210A meet all combinations of power delivery as currently
defined in the PCMCIA standard. The latest protocol accommodates mixed 3.3-V/5-V systems by first powering the card
with 5 V, then polling it to determine its 3.3-V compatibility. The PCMCIA specification requires that the capacitors on
3.3-V-compatible cards be discharged to below 0.8 V before applying 3.3-V power. This action ensures that sensitive 3.3-V
circuitry is not subjected to any residual 5-V charge and functions as a power RESET. PC Card specification requires that
VCC be discharged within 100 ms. PC Card resistance cannot be relied on to provide a discharge path for voltages stored
on PC Card capacitance because of possible high-impedance isolation by power-management schemes. The devices
include discharge transistors on all xVCC and xVPP outputs to meet the specification requirement.

SHUTDOWN MODE
In the shutdown mode, which can be controlled by SHDN or bit D8 of the input serial DATA word, each of the xVCC and
xVPP outputs is forced to a high-impedance state. In this mode, the chip quiescent current is reduced to 1 µA or less to
conserve battery power.
POWER-SUPPLY CONSIDERATIONS
These switches have multiple pins for each 3.3-V (except for the TPS2210A) and 5-V power input and for the switched
xVCC outputs. Any individual pin can conduct the rated input or output current. Unless all pins are connected in parallel,
the series resistance is higher than that specified, resulting in increased voltage drops and power loss. It is recommended
that all input and output power pins be paralleled for optimum operation.
To increase the noise immunity of the TPS2204A, TPS2206A, and TPS2210A, the power-supply inputs should be
bypassed with at least a 4.7-µF electrolytic or tantalum capacitor paralleled by a 0.047-µF to 0.1-µF ceramic capacitor. It
is strongly recommended that the switched outputs be bypassed with a 0.1-µF (or larger) ceramic capacitor; doing so
improves the immunity of the IC to electrostatic discharge (ESD). Care should be taken to minimize the inductance of PCB
traces between the devices and the load. High switching currents can produce large negative voltage transients, which
forward biases substrate diodes, resulting in unpredictable performance. Similarly, no pin should be taken below −0.3 V.
RESET INPUT
To ensure that cards are in a known state after power brownouts or system initialization, the PC Cards should be reset at
the same time as the host by applying low-impedance paths from xVCC and xVPP terminals to ground. A low-impedance
output state allows discharging of residual voltage remaining on PC Card filter capacitance, permitting the system (host
and PC Cards) to be powered up concurrently. The active low RESET input closes internal ground switches S1, S4, S7,
and S11 with all other switches left open. The devices remain in the low-impedance output state until the signal is
deasserted and new data is clocked in and latched. The input serial data cannot be latched during reset mode. RESET
is provided for direct compatibility with systems that use an active-low reset voltage supervisor. The RESET pin has an
internal 150-k pullup resistor.
CALCULATING JUNCTION TEMPERATURE
The switch resistance, rDS(on), is dependent on the junction temperature, TJ, of the die. The junction temperature is
dependent on both r DS(on) and the current through the switch. To calculate TJ, first find rDS(on) from Figures 26 through 28,
using an initial temperature estimate about 30°C above ambient. Then calculate the power dissipation for each switch,
using the formula:
PD+rDS(on) I2
Next, sum the power dissipation of all switches and calculate the junction temperature:
TJ+ǒȍPD RqJAǓ)TA,R
qJA +108°CńW
Compare the calculated junction temperature with the initial temperature estimate. If the temperatures are not within a few
degrees of each other, recalculate using the calculated temperature as the initial estimate.

LOGIC INPUTS AND OUTPUTS
The serial interface consists of the DATA, CLOCK, and LATCH leads. The data is clocked in on the positive edge of the
clock (see Figure 2). The 9-bit (D0−D8) serial data word is loaded during the positive edge of the latch signal. The latch
signal should occur before the next positive edge of the clock.
The shutdown bit of the data word places all VCC and Vpp outputs in a high-impedance state and reduces chip quiescent
current to 1 µA to conserve battery power.
The serial interface is designed to be compatible with serial-interface PCMCIA controllers and current PCMCIA and Japan
Electronic Industry Development Association (JEIDA) standards.
An overcurrent output (OC) is provided to indicate an overcurrent or overtemperature condition in any of the VCC and VPP
outputs as previously discussed.

USING THE DEVICES WITH 11-BIT SERIAL DATA INTERFACE CONTROLLERS
Even though the control logic table only shows a 9-bit interface, it can be used with most 11-bit serial data interface
controllers. With the use of the latch input, the TPS2204A, TPS2206A, and TPS2210A only latch the last 9 bits from the
serial stream. This means that for an 11-bit serial stream, bits 9 and 10 are ignored. 11-bit serial interface controllers use
bits 9 and 10 for independent voltage selection of 3.3 V and 5 V between xVCC and xVPP.
ESD PROTECTIONS (see FIGURE 37)
All TPS2206A inputs and outputs of these devices incorporate ESD-protection circuitry designed to withstand a 2-kV
human-body-model discharge as defined in MIL-STD-883C, Method 3015. The xVCC and xVPP outputs can be exposed
to potentially higher discharges from the external environment through the PC Card connector . Bypassing the outputs with
0.1-µF capacitors protects the devices from discharges up to 10 kV.

12-V FLASH MEMORY SUPPLY
The TPS6734 is a fixed 12-V output boost converter capable of delivering 120 mA from inputs as low as 2.7 V. The device
is pin-for-pin compatible with the MAX734 regulator and offers the following advantages: lower supply current, wider
operating input-voltage range, and higher output currents. As shown in Figure 36, the only external components required
are: an inductor, a Schottky rectifier, an output filter capacitor, an input filter capacitor, and a small capacitor for loop
compensation. The entire converter occupies less than 0.7 in2 of PCB space when implemented with surface-mount
components. An enable input is provided to shut the converter down and reduce the supply current to 3 µA when 12 V is
not needed.
The TPS6734 is a 170-kHz current-mode PWM (pulse-width modulation) controller with an n-channel MOSFET power
switch. Gate drive for the switch is derived from the 12-V output after start-up to minimize the die area needed to realize
the 0.7- MOSFET and improve efficiency at input voltages below 5 V. Soft start is accomplished with the addition of one
small capacitor. A 1.22-V reference, pin 2 of TPS6734, is brought out for external use. For additional information, see the
TPS6734 data sheet (SLVS127).
NOTE A: The enable terminal can be tied to a general-purpose I/O terminal on the PCMCIA controller or tied high.
