DESCRIPTION
When CHRG_POL pin is at GND then CHRG_DET is in active low open-drain mode with external RCHRGDET
35 F2 CHRG_DET D O V
BAT
(100K) connected to VBAT. When CHRG_POL pin is at VBAT then CHRG_DET is in active high open-source
mode with external RCHRGDET (100K) connected to GND. This pin is 5V tolerant.
Controls an external, active high, VBUS power switch or charge pump. Open source output on VBAT supply
36 D4 PSW D O V
BAT
when PSW_OSOD bit is 0 (default), open-drain active-low output when PSW_OSOD bit is 1. Requires an
external RPSW (100K) pull down/up resistor to GND/VBAT .
