General Description
The MAX8533 is a single-port, 12V, InfinibandTM-compli-
ant (IB) versatile hot-swap controller. The device can be
implemented in both IB Class I (nonisolated) and Class II
(isolated) power-topology applications. Additionally, the
MAX8533 can be used as a reliable power controller on
hot-swappable blade servers, RAID cards, and network
switches or routers that are powered from a 12V bus.
The MAX8533 integrates several features that allow reli-
able insertion and removal of the circuit card, as well as
real-time monitoring of abnormal occurrences. The
MAX8533 allows for an adjustable soft-start ramp during
turn-on of the input voltage, while providing overcurrent
protection. It also provides accurate and consistent cur-
rent-regulated outputs for a programmable period of time
to latch off and soft-start in the presence of overcurrent
conditions (OC). Additionally, it provides a second level
of severe overcurrent (SOC) protection by responding to
a dead short in 100ns. The MAX8533 also includes
adjustable overvoltage protection.
The MAX8533 incorporates undervoltage lockout
(UVLO) and a power-good (POK) signal to the DC-to-
DC converters to confirm the status of output voltage
rails during operation. Two enable inputs EN (logic
enable) and LPEN (local power enable) provide flexible
sequencing. The MAX8533 is specified across the
extended temperature range and has an absolute maxi-
mum rating of 16V to withstand inductive kickback dur-
ing board removal.
The MAX8533 is available in the space-saving 10-pin
µMAX package.

PIN NAME FUNCTION
1 ISET Current-Limit Threshold Programming Input. Connect to the low side of the current-limit threshold
programming resistor.
2 IN Bulk Power Supply. Connect to the input power supply and positive terminal of the current-sense resistor.
3 GATE
External MOSFET-Gate-Drive Output. Connect to the gate of the external N-channel MOSFET. A series
resistor and capacitor connected from GATE to RET sets the turn-on ramp rate. At turn-on, this capacitor is
charged to VIN + 5V (typ) by an internal current source. GATE is pulled to RET when EN is high and/or LPEN
is low. GATE is pulled to RET during a fault condition.
4 CTIM
Current Regulation Time Programming Input. Connect a capacitor from CTIM to RET. The capacitance at
CTIM determines the time delay between an overcurrent event and chip output shutdown (current-limit
timeout). CTIM is pulled low, resetting the fault latch when either EN is high or LPEN is low.
5 RET Bulk Power Ground
6 OVP Overvoltage Protection Input. Connect to common point of a resistor-divider from OUT to RET. GATE pulls
low when VOVP exceeds the 2V threshold for at least 1.5ms and the IC is latched off.
7 OUT Output Voltage. Connect to the output of the circuit.

9 LPEN Local Power-Enable Input. LPEN is a positive-assertion enable input to turn on the IC. Pull LPEN low to

10 EN Chip-Enable Input. EN is an active-low input that enables the IC.
Detailed Description
The MAX8533 is a single-port, 12V, IB-compliant versa-
tile hot-swap controller IC designed for applications
where a line card is inserted into a live backplane. The
MAX8533 can be implemented in both IB Class I (non-
isolated) and Class II (isolated) power-topology appli-
cations. Normally, when a line card is plugged into a
live backplane, the low impedance of the cards dis-
charged filter capacitors can momentarily collapse the
input supply voltage. The MAX8533 is designed to
reside on the line card and to provide inrush current-
limiting and short-circuit protection. This is achieved
using an external N-channel MOSFET, current-sense
resistor, and current-limit set resistor, along with two
on-chip comparators (Figure 1).
UVLO and Startup
The MAX8533 has an undervoltage lockout protection
circuit. The circuit is disabled when VIN is below 8.4V
(typ). The gate of the MOSFET, CTIM, LPEN, and POK is
pulled to RET until VIN exceeds the UVLO threshold.
Once VIN exceeds the UVLO threshold and LPEN and
EN are enabled, the capacitor on the gate of the exter-
nal MOSFET is charged and the MOSFET turns on. The
charging of this capacitor provides soft-start to prevent
high inrush currents.
On/Off Control
The MAX8533 is enabled/disabled using LPEN and EN.
Drive EN low and LPEN high to enable the device. LPEN
can also be left unconnected as it is internally connected
to 5V. Drive LPEN low or EN high to disable the output.
Table 1 is the truth table for these inputs.
EN LPEN OUTPUT
0 0 OFF
01ON
1 0 OFF
1 1 OFF
Table 1. Truth Table
Zero is a logic-low input, 1 is a logic-high input or unconnected
input.
Startup Into Load
The MAX8533 is intended to be used in a circuit where
no load is applied until the POK signal is enabled. In an
application where the load is applied during the output-
voltage ramp up, the RDS(ON) of the MOSFET is higher
and the power dissipated by the MOSFET is larger.
Repeated, rapid hot-swaps into a load can create suffi-
cient heat to exceed the power-dissipation limits of the
package causing failure of the MOSFET.
Applications Information
Setting the Turn-On Ramp Rate
The MOSFET turn-on ramp rate is determined by the
capacitor (C2) at GATE (Figure 2). An internal 10µA
current source charges C2 to bring GATE high. The
soft-start rate is determined as follows:
tSS = C2 x (VIN + 5)/(10 x 10-6)
tSS may be longer than expected in the application
depending on the gate capacitance of the external
MOSFET. The necessary gate voltage is provided by
an on-board charge pump that boosts the voltage at
GATE to (VIN + 5V).
External Power MOSFET Selection
Select the N-channel MOSFET according to the appli-
cations current requirements. Table 2 lists some rec-
ommended components. The MOSFETs on-resistance
(RDS(ON)) should be chosen low enough to have a min-
imal voltage drop at full load to limit the MOSFET power
dissipation. High RDS(ON) can cause high output ripple
if the board has pulsing loads, or trigger an external

undervoltage reset monitor at full load. The maximum
gate voltage (VGS) rating must be at least ±20V. Low
MOSFET gate capacitance is not necessary for the
inrush current limiting because it is achieved by limiting
the GATE dV/dt. However, higher gate capacitance
increases the turn-off time of the MOSFET under fault
conditions.
Current-Limit and Overload Protection
The MAX8533 features a dual overcurrent protection
circuit that turns off the MOSFET in overcurrent situa-
tions. When an overload event is sensed, the IC limits
the current to a level set by ISET. Continuous overload
for a period set by the user (tCTIM) latches off the
MOSFET. The severe overcurrent protection immediate-
ly shuts down the external MOSFET and latches it off.
R3 sets the current-limit threshold voltage. This voltage
is generated from an internal 20µA source driven
through R3. Therefore:
VILIM = R3 x 20µA
The current-sense signal is sensed across resistor R1.
With no load, the voltage at ISET is the input voltage
plus VILIM. As the load current increases, the voltage
drop across R1 increases and reduces the voltage at
ISET. Once VISET is lower than VIN, the overcurrent
comparator (Figure 1) is tripped and the MAX8533
enters current regulation mode. During current regula-
tion mode, the gate voltage of the MOSFET is
decreased to limit the current to the output. The maxi-
mum time period for the current regulation mode is set
by the external capacitor at CTIM (C3). This feature
allows transient currents that exceed the current limit to
pass without shutting down the circuit. The current regu-
lation time period is determined as:
tIREG = C3 x (1.8V/20µA)
If tIREG expires and the overcurrent condition still
exists, the MOSFET is latched off.
The severe overcurrent comparator (Figure 1) trips if
the drop across the current-sense resistor (R1) is
150mV higher than the current-limit threshold (VIN
exceeds VISET by 150mV). During a severe overcurrent
event, the gate of the external MOSFET is pulled down
with a 350mA current source and latched immediately.
Toggle EN, LPEN, or input power to clear the latched
fault condition.
Overvoltage Protection
The MAX8533 has an adjustable overvoltage protection
feature that latches the IC off in case of an overvoltage
event. An external resistor-divider (R4 and R5, Figure 2)
from OUT to RET with OVP connected to the center,
sets the overvoltage threshold. Use 4.99kfor R4. R5
is determined using the following equation:
R5 = 4.99 x 103x ((VOVT / VOVP) - 1)
VOVT is the desired overvoltage threshold and VOVP is
2V (typ). OVP latches off the MAX8533 if an overvoltage
condition exists for 1.5ms. Toggle EN, LPEN, or input
power to clear the latched fault condition.
Fault Reset
Overcurrent, severe overcurrent, and overvoltage con-
ditions result in the MAX8533 entering a latched fault
condition. Toggle LPEN, EN, or input power to reset the
latched fault condition and return to normal operation.
Power-Good Output (POK)
POK is an open-drain output used to enable the on-
board DC-to-DC converter. The POK output turns high
impedance when the output rail reaches 9.6V. POK
must be pulled up to the users logic level using a
pullup resistor.

_______PC Board Layout Guidelines
To take advantage of the switch response time to an
output fault condition, keep all traces as short as possi-
ble and maximize the high-current trace width to
reduce the effect of undesirable parasitic inductance.
The MOSFET dissipates a fair amount of heat due to
the high currents involved, especially during an over-
current condition. In order to dissipate the heat gener-
ated by the MOSFET, make the power traces very wide
with a large amount of copper area. A more efficient
way to achieve good power dissipation on a surface-
mount package is to lay out two copper pads directly
under the MOSFET package on both sides of the
board. Connect the two pads to the ground plane
through vias, and use enlarged copper mounting pads
on the top side of the board.
Minimize the current-sense resistor trace length
(<10mm), and ensure accurate current sensing with
Kelvin connections. Place capacitor CTIM as close as
possible to the IC. The traces from the current-sense
resistor to IN and ISET should be as short as possible
for accurate current sensing. Place the MAX8533 cir-
cuit as close as possible to the backplane connector. A
sample PC board layout is available in the MAX8533
Evaluation Kit.
