BQ24773: ACDET is good, but ACOK seems quite strange.

Jerry Chu

Part Number: BQ24773

Hi Expert,

Plug in 12V power and no I2C control, no battery insert. ACDET>3.0V, but ACOK got the pulses. Can you help to check it? Thanks!

Jerry,

ACDET>2.4V is only one of the condition making ACOK change. Please check VCC and Vsrn to make sure: VCC is lower than Vacovp and Vsrn is lower than VCC.
