Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 SW_OPEN O USB switch status indicator
Open-drain output. 10kΩ external pull-up resistor required
SW_OPEN = LOW indicates when switch is connected
SW_OPEN = HIGH-Z indicates when then switch is not connected
2 DM_HOST I/O D– signal to transceiver
3 DP_HOST I/O D+ signal to transceiver
4 CHG_AL_N O Charging status indicator
Open-drain output. 10kΩ external pull-up resistor required
CHG_AL_N = LOW indicates when charging is allowed
CHG_AL_N = HIGH-Z indicates when charging is not allowed
5 GOOD_BAT I Battery status indication from system
GOOD_BAT = LOW indicates a dead battery
GOOD_BAT = HIGH indicates a good battery
6 GND - Ground
7 DP_CON I/O D+ signal from USB connector
8 DM_CON I/O D– signal from USB connector
9 VBUS I Supply pin from USB connector
10 CHG_DET O Charger detection indicator
Push-Pull output to system
CHG_DET = LOW indicates when a charger is not detected
CHG_DET = HIGH indicates when a charger detected
