FUNCTION
Input Limiter-Control Input 1. Used with CEN and PEN2 to set the DC current limit to 95mA,
475mA, a resistor programmable level up to 2A, or to turn off the input limiter (see Table 1).
Input Limiter-Control Input 2. Used with CEN and PEN1 to set the DC current limit to 95mA,
475mA, a resistor programmable level up to 2A, or to turn off the input limiter (see Table 1).
Enable Input and PWM Dimming Input for Regulator 3 White LED Boost. Drive high to

enable. Drive low for more than 2ms to turn off. For PWM-controlled dimming, drive EN3
with a PWM switching input with a frequency of 1kHz to 100kHz.

DC1,
DC2
DC Input Source. Connect to an AC adapter or USB source. DC1 and DC2 are internally
connected.
System Supply Voltage. The SYS output supplies power to all regulators. With no external

SYS1,
SYS2
power, SYS1 and SYS2 connect to BAT through an internal 40m ? switch. When a valid
voltage is present at DC_, SYS_ connects to DC_ but is limited to 5.3V. SYS1 and SYS2 are
internally connected.
8, 9
7, 8
BAT1,
BAT2
Battery Connections. Connect to a single-cell Li+ battery. The battery is charged from SYS_
when a valid source is present at DC. BAT_ drives SYS_ when DC is not valid. BAT1 and
BAT2 are internally connected.
LED Analog Brightness Control Input. Connect BRT to a voltage from 50mV to 1.5V to set
10

BRT
I CS from 1mA to 30mA. Connect BRT to the center of a resistor-divider connected between
REF and GND to set a fixed brightness when analog dimming is not required.
Charger Status Output. CHG is an open-drain nMOS that pulls low when the charger is in
11

CHG
fast charge or prequalification modes. CHG goes high impedance when the charger is in
top-off mode or disabled.
Charger Enable Input. Drive CEN low to enable the charger when a valid source is
12
10
CEN
connected at DC. Drive CEN high to disable charging. Drive CEN high and PEN2 low to
enter USB suspend mode.
Thermistor Input. Connect a 10k ? negative temperature coefficient (NTC) thermistor from
13
11
THM
THM to GND. Charging is suspended when the temperature is beyond the hot or cold
limits. Connect THM to GND to disable the thermistor functionality.
Charge Rate-Set Input. Connect a resistor from ISET to GND to set the fast-charge current
14
12
ISET
from 300mA to 1.25A. The prequalification charge current and top-off threshold are set to
10% and 7.5% of fast-charge current, respectively.
Charge Timer-Programming Pin. Connect a capacitor from CT to GND to set the length of
15
13
CT
time required to trigger a fault condition in fast-charge or prequalification mode and to
determine the time the charger remains in top-off mode. Connect CT to GND to disable
timers.

REF
GND
Reference Voltage. Provides 1.5V output when EN3 is high. An internal discharge
resistance pulls REF to 0V when EN3 is low.
Ground. Low-noise ground connection.
Linear Regulator 4 Output. Delivers up to 500mA at an output voltage determined by SL1

OUT4
and SL2. Connect a 4.7μF ceramic capacitor from OUT4 to GND. Increase the value to
10μF if V OUT4 < 1.5V.
