BQ24072: Charge timer reset conditions

yuji.S

Part Number: BQ24072

Hello,

I am going to use BQ24072 at standallone mode.

Could you teach me charge timer reset condition?

I found out thay It's written "Reset the timers by toggling the CE pin, or by toggling EN1, EN2 pin to put the device in and out of USB suspend mode (EN1 = HI, EN2 = HI)." on your specification sheet.

I think that BQ24072 has other timer reset condions.

for example, I think BQ24072's charge timer reset at under following timing.

"If VBAT < VRCH,then the protector closed and charging is initiated."

"When no source is connected to the IN input,"

Best Regards.,

Yuji,
The timers are reset at the beginning of every power cycle so every time a source is connected to IN, the timer resets. The timer resets at the beginning of every charge cycle.
