BQ24707 datasheet
PIN 5 ACOK
AC adapter detect open drain output. It is pulled LOW to GND by an internal MOSFET when the voltage on the
ACDET pin is above 2.4V, voltage on the VCC pin is above UVLO and voltage on the VCC pin is 245mV above the
5 ACOK voltage on the SRN pin, indicating a valid adapter is present to start charge. If any one of the above conditions cannot
meet, it is pulled HIGH to the external pull-up supply rail by an external pull-up resistor. Connect a 10kΩ pull-up
resistor from the ACOK pin to the pull-up supply rail.
