High Input Voltage Charger
Features
The ISL6294 is a cost-effective, fully integrated 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.
• Complete Charger for Single-Cell Li-ion/Polymer Batteries
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.
• Programmable End-of-Charge Current
Two 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 leakage
current from the battery.

5. The charge current can be affected by the thermal foldback function if the IC under the test setup cannot dissipate the heat.
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 opendrain 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 disable or
enable the charger. Drive to HIGH to disable the charger.
When this pin is driven to LOW or left floating, the charger is
enabled. This pin has an internal 200kΩ pull-down resistor.
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:
12089
I REF = ----------------R IREF
( mA )
(EQ. 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 - Charger 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.
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:

FIGURE 4. TYPICAL CHARGE PROFILE
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 tricklecharge threshold, the ISL6294 charges the 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
5
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
FN9174.4
July 9, 2007
ISL6294
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 surge after EOC
can be caused by a load connected to the battery.
CHG Indication
A thermal foldback function reduces the charge current
anytime when the die temperature reaches typically +115°C.
This function guarantees safe operation when the printed
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.
EN Input
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 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
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 opendrain 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 with 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 VOS is the offset 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.
6
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 monitoring 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 current. 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 for stability and 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.

LIMITED
CHARGE CURRENT (mA)
The input capacitor is required to suppress the power supply
transient response during transitions. Mainly this capacitor is
selected to avoid oscillation during the start up when the
input supply is passing the POR threshold and the VIN - BAT
comparator offset voltage. When the battery voltage is above
the POR threshold, the VIN - VBAT offset voltage dominates
the hysteresis value. Typically, a 1µF X5R ceramic capacitor
should be sufficient to suppress the power supply noise.

The criteria for selecting the output capacitor is to maintain
the stability of the charger as well as to bypass any transient

output is dependent on the actual application requirement.

INPUT VOLTAGE (V)
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-linearity 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 thermal foldback function. The limit
caused by the thermal limit is dependent on the thermal
impedance. As the thermal impedance increases, the
thermal-limited curve moves towards left, as shown in
Figure 1.

FIGURE 1. CHARGE CURRENT LIMITS IN THE CC MODE
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. Typically 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 Sources
The input power source is typically a well-regulated wall
cube with 1-meter 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.
