NAME
DESCRIPTION
A1
VLDO1
O Output voltage of LDO1
A2
HOLD_LDO1
I Power-on input for LDO1. When pulled HIGH, LDO1 is kept enabled after PB_IN was released HIGH.
A3
GPIO3
I/O General purpose I/O or 5-mA current sink
A4
GPIO1
I/O General purpose I/O
A5
SCLK
I
Clock input for the I²C interface
B1
VINLDO1
I Input voltage for LDO1
B2
VBAT/TS_OUT
O Output of battery temperature and battery voltage monitor
B3
GPIO2
I/O General purpose I/O or 5-mA current sink
B4
GPIO0
I/O General purpose I/O
B5
SDAT
I/O Data line for the I²C interface
C1
AGND
— Analog ground
C2
TS
I Connect a thermistor from this pin to GND for battery temperature
C3
INT
O Open-drain interrupt output
C4
PB_IN
I Push button input; Turns on DCDC1 and LDO1 if pulled to GND.
C5
RESET
O
Open-drain output of the reset generator; This output goes active LOW when the output voltage of LDO1 falls 8% below its target
voltage.
D1
FB_DCDC1
I Feedback input of step-down converter
D2
HOLD_DCDC1
I Power-on input for DCDC1 converter. When pulled HIGH, the DC-DC converter is kept enabled after PB_IN was released HIGH.
D3
BAT
I/O Connect to battery + terminal
D4
SYS
O System voltage; output of the power path manager. Power input for step-down converter DCDC1
D5
ISET
I Connect a resistor from this pin to GND to set fast charge current
E1
PGND
— Power ground
E2
L1
O Switch output of step-down converter
E3
BAT
I/O Connect to battery + terminal
E4
SYS
O System voltage; output of the power path manager. Power input for step-down converter DCDC1
E5
AC
I Input power for power manager, connect to external DC supply.
