Part Number: BQ76952

I have a query abhout BQ76952 need your help.

I want to set the MOS turn off when meet protection, and manually turn on, not automacilly turn on when achieve the recover condition.

How to set?

Thanks

Hi Star,

The recommended method is described in the TRM:

For example, they can use logic similar to this:

Hi Matt

Thanks for your reply.

I want to know how to control MOS only by host, when in protection the chip will not recover until host send the commands.

Thanks

Hello Star,

The method that Matt recommended is how you would control the MOSFETs using a host. The FETs will be triggered during a fault autonomously by the BQ76952, in order to keep the FETs off you need to send the commands described by Matt.

Then to recover the FETs manually you'd send the FETs ON command as Matt had described and shown.
