BQ76952: How to use standalone?

BQ76952: How to wake up by connecting a load or charger

Hi,

Is it mandatory to use TS2 pin to wake up BQ76952 when used as a standalone one?

If it is not, then kindly let me know how to wake up the IC by connecting a charger or a load to the battery pack.

Thank you,

Prasad M

    Hi Prasad,

    The BQ76952 will wake from pull down of the TS2 pin, or pull up of the LD pin, see the data sheet for details.  Connecting a charger which outputs a voltage will typically pull up the LD pin and provide a suitable wake up.  For systems where this does not occur, provide a suitable control circuit to detect the desired condition and pull down TS2.
