BQ76PL455A-Q1: Does GPIO of BQ76PL455A-Q1 OCP and OVP function?

Part Number: BQ76PL455A-Q1

Dear Sir:

                We want to used BQ76PL455A-Q1 to do 96V(48V battery module x2) BMS application. Does BQ76PL455A-Q1 can use GPIO for UVP and OVP alarm? BTW , Our system BD as below , Does TI have some suggest to us?

Best Regard

Jason

  • what is the intent of bypassing the built-in capability of OV, UV of the bq76PL455-q1 ? you unwanted cost to the overall system! adding complexity. Adding a nMOS on the return of high-current path, can have issues, when its OPEN.

    Depending on the application and qualification, take a look at TI's BQ769x0 family for your needs too.

    hope this helps,
