BQ79600-Q1: Reverse Wakeup condition

Alex Wu

Part Number: BQ79600-Q1

Tool/software:

Hi Expert

if VIO voltage=0V,BAT (15pin) voltage=5.5~18V, device whether can trigger reverse wakeup function that mean is INH(16pin) can output wake up signal?

why datasheet depiction use reverse wakeup feature is powered by "12V" ?

Alex,

If you have VBAT shorted to CVDD, then you cannot use reverse wakeup.
If you have VBAT connected to a supply, then you can use reverse wakeup.

Quentin,

Yes, we choose VBAT connected to a supply.However, what confuses us is the minimum operating voltage.

The spec define is 5.5v minimum, but test condition is need 12V.

Alex,

The "12V Battery" is just referencing the type of input.
This feature is not supported when using a 5V regulated supply.

Please follow the Min and Max supplies that are outlined (5.5V - 24V).

Best,

Quentin
