ISL6294

High Input Voltage Charger

The ISL6294 is a cost-effective, fully integrate d high input

voltage single-cell Li-ion battery charger . The charger uses a

CC/CV charge profile required by Li-ion batteries. The

charger accepts an input voltage up to 28V but is disabled

when the input voltage exceeds the OVP threshold, typically

6.8V, to prevent excessive power dissipation. The 28V rating

eliminates the overvoltage protection circuit required in a low

input voltage charger.

The charge current and the end-of-charge (EOC) current are

programmable with external resistors. When the battery voltage

is lower than typically 2.55V, the charger preconditions the

battery with typically 20% of the programmed charge current.

When the charge current reduces to the programmable EOC

current level during the CV charge phase, an EOC indication is

provided by the CHG pin, which is an open-drain output. An

internal thermal foldback function protects the charger from any

thermal failure.

T wo indication pins (PPR and CHG) allow simple interface to

a microprocessor or LEDs. When no adapter is attached or

when disabled, the charger draws less than 1µA leakag e

current from the battery.

Pin Descriptions

VIN - Power input. The absolute maximum input voltage is

28V. A 0.47µF or larger value X5R ceramic capacitor is

recommended to be placed very close to the input pin for

decoupling purpose. Additional capacitance may be required

to provide a stable input voltage.

PPR - Open-drain power presence indication. The open-

drain MOSFET turns on when the input voltage is above the

POR threshold but below the OVP threshold and off

otherwise. This pin is capable to sink 10mA (minimum)

current to drive an LED. The maximum voltage rating for this

pin is 7V. This pin is independent on the EN-pin input.

CHG - Open-drain charge indication pin. This pin outputs a

logic LOW when a charge cycle starts and turns to HIGH

when the end-of-charge (EOC) condition is qualified. This

pin is capable to sink 10mA minimum current to drive an

LED. When the charger is disabled, the CHG outputs high

impedance.

EN - Enable input. This is a logic input pin to disabl e or

enable the charger. Drive to HIGH to disable the charger.

When t his pin is dr ive n t o LOW o r lef t floating, the charger is

enabled. This pin has an internal 200kΩ pull-down resistor.

GND - System ground.

IMIN - End-of-charge (EOC) current program pin. Connect a

resistor between this pin and the GND pin to set the EOC

current. The EOC current IMIN can be programmed by the

Equation 1:

Where RIMIN is in kΩ. The programmable range covers 5%

(or 10mA, whichever is higher) to 50% of IREF. When

programmed to less than 5% or 10mA, the stability is not

guaranteed.

IREF - Charge-current program and monitoring pin. Connect

a resistor between this pin and the GND pin to set the

charge current limit determined by the Equation 2:

Where RIREF is in kΩ. The IREF pin voltage also monitors

the actual charge current during the entire charge cycle,

including the trickle, constant-current, and constant-voltage

phases. When disabled, VIREF = 0V.

BAT - Cha rger output pin . Connect this pin to the battery. A

1µF or larger X5R ceramic capacitor is recommended for

decoupling and stability purposes. When the EN pin is pulled

to logic HIGH, the BAT output is disabled.

EPAD - Exposed pad. Connect as much as possible copper

to this pad either on the component layer or other layers

through thermal vias to enhance the thermal performance.

Description

The ISL6294 charges a Li-ion battery using a CC/CV profile.

The constant current IREF is set with the external resistor

RIREF (See Figure 1) and the constant voltage is fixed at

4.2V. If the battery voltage is below a typical 2.55V trickle-

charge threshold, the ISL6294 charges th e battery with a

trickle current of 19% of IREF until the battery voltage rises

above the trickle charge threshold. Fast charge CC mode is

maintained at the rate determined by programming IREF until

the cell voltage rises to 4.2V. When the battery voltage

reaches 4.2V, the charger enters a CV mode and regulates

the battery voltage at 4.2V to fully charge the battery without

the risk of over charge. Upon reaching an end-of-charge

(EOC) current, the charger indicates the charge completion

with the CHG pin, but the charger continues to output the

4.2V voltage. Figure 4 shows the typical charge waveforms

after the power is on.

The EOC current level IMIN is programmable with the

external resistor RIMIN (See Figure 1). The CHG signal turns

to LOW when the trickle charge starts and rises to HIGH at

the EOC. After the EOC is reached, the charge current has

to rise to typically 76% IREF for the CHG signal to turn on

again, as shown in Figure 4. The current surg e after EOC

can be caused by a load connected to the battery.

A thermal foldback functi on re duces the charge current

anytime when the die te mpera ture reaches typica lly +115°C.

This function guarantees safe operation when the p rinte d

circuit board (PCB) is not capable of dissipating the heat

generated by the linear charger . The ISL6294 accepts an input

voltage up to 28V but disables charging when the input

voltage exceeds the OVP threshold, typically 6.8V, to protect

against unqualified or faulty AC adapters.

PPR Indication

The PPR pin is an open-drain output to indicate the

presence of the AC adapter. Whenever the input voltage is

higher than the POR threshold, the PPR pin turns on the

internal open-drain MOSFET to indicate a logic LOW signal,

independent on the EN pin input. When the internal open-

drain FET is turned off, the PPR pin should leak less than

1µA current. When turned on, the PPR pin should be able to

sink at least 10mA current under all operating conditions.

The PPR pin can be used to drive an LED (see Figure 1) or

to interface wi th a microprocessor.

Power-Good Range

The power-good range is defined by the following three

conditions:

1. VIN > VPOR

2. VIN - VBAT > VOS

3. VIN < VOVP

where the V OS is the of fset voltage for the input and output

voltage comparator, discussed shortly, and the VOVP is the

overvoltage protection threshold given “Electrical

Specifications” on page 2. All VPOR, VOS, and VOVP have

hysteresis, as given in “Electrical Specifications” on page 2.

The charger will not charge the battery if the input voltage is

not in the power-good range.

Input and Output Comparator

The charger will not be enabled unless the input voltage is

higher than the battery voltage by an offset voltage VOS.

The purpose of this comparator is to ensure that the charger

is turned off when the input power is removed from the

charger. Without this comparator, it is possible that the

charger will fail to power down when the input is removed

and the current can leak through the PFET pass element to

continue biasing the POR and the Pre-Regulator blocks

shown in the Block Diagram on page 5.

CHG Indication

The CHG is an open-drain output capable to at least 10mA

current when the charger starts to charge and turns off when

the EOC current is reached. The CHG signal is interfaced

either with a micro-processor GPIO or an LED for indication.

EN Input

EN is an active-low logic input to enable the charger. Drive

the EN pin to LOW or leave it floating to enable the charger.

This pin has a 200kΩ internal pulldown resistor so when left

floating, the input is equivalent to logic LOW . Drive this pin to

HIGH to disable the charger . The threshold for HIGH is given

in “Electrical Specifications”on page 2.

IREF Pin

The IREF pin has the two functions as described in the Pin

Description section. When setting the fast charge current,

the charge current is guaranteed to have 10% accuracy with

the charge current set at 500mA. When monitori ng the

charge current, the accuracy of the IREF pin voltage vs the

actual charge current has the same accuracy as the gain

from the IREF pin current to the actual charge curre nt. The

accuracy is 10% at 500mA and is expected to drop to 30% of

the actual current (not the set constant charge current) when

the current drops to 50mA.

Operation Without the Battery

The ISL6294 relies on a battery fo r stability an d is not

guaranteed to be stable if the battery is not connected. With

a battery, the charger will be stable with an output ceramic

decoupling capacitor in the range of 1µF to 200µF. The

maximum load current is limited by the dropout voltage or

the thermal foldback.

Dropout Voltage

The constant current may not be maintained due to the

rDS(ON) limit at a low input voltage. The worst case on

resistance of the pass FET is 1.2Ω the maximum operating

temperature, thus if tested with 0.5A current and 3.8V

battery voltage, constant current could not be maintained

when the input voltage is below 4.4V.

Thermal Foldback

The thermal foldback function starts to reduce the charge

current when the internal temperature reaches a typical

value of +115°C .

Applications Information

Input Capacitor Selection

The input capacitor is required to suppress the power supply

transient response during transitions. Mainly this capacitor is

selected to avoid oscillation durin g the start up when the

input supply is passing the POR threshold and the VIN - BA T

comparator of fset voltage. When the battery voltage is above

the POR threshold, the VIN - VBAT offset voltage dominates

the hysteresis value. T ypically, a 1µF X5R ceramic capacitor

should be sufficient to suppress the power supply noise.

Output Capacitor Select ion

The criteria for selecting the output capacitor is to maintain

the stability of the charger as well as to bypass any transient

load current. The minimum capacitance is a 1µF X5R

ceramic capacitor. The actual capacitance connected to the

output is dependent on the actual application requirement.

Charge Current Limit

The actual charge current in the CC mode is limited by

several factors in addition to the set IREF. Figure 1 shows

three limits for the charge current in the CC mode. The

charge current is limited by the on resistance of the pass

element (power P-Channel MOSFET) if the input and the

output voltage are too close to each other. The solid curve

shows a typical case when the battery voltage is 4.0V and

the charge current is set to 700mA. The non-lineari ty on the

rON-limited region is due to the increased resistance at

higher die temperature. If the battery voltage increases to

higher than 4.0V, the entire curve moves towards right side.

As the input voltage increases, the charge current may be

reduced due to the th ermal foldback function. T he limit

caused by the thermal limit is dependent on the thermal

impedance. As the thermal impedance increases, the

thermal-limited curve moves towards lef t, as shown in

Figure 1.

Layout Guidance

The ISL6294 uses a thermally-enhanced DFN package that

has an exposed thermal pad at the bottom side of the

package. The layout should connect as much as possible to

copper on the exposed pad. T ypically the component layer is

more effective in dissipating heat. The thermal impedance

can be further reduced by using other layers of copper

connecting to the exposed pad through a thermal via array.

Each thermal via is recommended to have 0.3mm diameter

and 1mm distance from other thermal vias.

Input Power Source s

The input power source is typically a wel l-regulated wall

cube with 1-mete r length wire or a USB port. The input

voltage ranges from 4.25V to 6.5V under full-load and

unloaded conditions. The ISL6294 can withstand up to 28V

on the input without damaging the IC. If the input voltage is

higher than typically 6.8V, the charger stops charging.
