DESCRIPTION
NAME
NO.
D+
24
AIO
Positive USB data line – D+/D– based USB host/charging port detection. The detection includes
data contact detection (DCD) and secondary detection in BC1.2.
D–
1
AIO
Negative USB data line – D+/D– based USB host/charging port detection. The detection includes
data contact detection (DCD) and secondary detection in BC1.2.
STAT
2
DO
Open drain charge status indicator – Connect to the pull-up rail via 10-k
Ω resistor. LOW indicates
charge in progress. HIGH indicates charge complete or charge disabled. When any fault occurs, the
STAT pin blinks at 1Hz. The STAT function can be disabled when the STAT_DIS bit is set.
CE
3
DI
Active Low Charge Enable Pin – Battery charging is enabled when EN_CHG bit is 1 and CE pin is
LOW. CE pin is internally pulled low with 900k-Ω resistor.
SDA
4
DIO
I2C Interface Data – Connect SDA to the pull up rail through a 10-k
Ω resistor.
SCL
5
DI
I2C Interface Clock – Connect SCL to the pull up rail through a 10-k
Ω resistor.
INT
6
DO
Open drain active Interrupt Output – Connect INT to the pull up rail via a 10-k
Ω resistor. The INT
pin sends active low, 256-µs pulse to the host to report charger device status and fault.
TS
7
AI
Temperature Qualification Voltage – Connect a negative temperature coefficient thermistor.
Program temperature window with a resistor divider from REGN to TS to GND. Charge suspends
when TS pin is out of range. Recommend 103AT-2 thermistor.
