BQ76952: AFE BQ76952

Kish V

Part Number: BQ76952

Hi,

Can you please let me know the FIT rate of BQ76952?

Is there any configuration where if communication is lost with MCU (I2C) then AFE can enter into safe state (Open both FET)?

And the loss of communication time configuration?

Pros and cons of using FET drive to control MOSFET.

Regards,

Kish

Hi Kish,

You can find the FIT rate estimator here: MTBF and FIT Rate Estimator.

The bq76952 includes host watchdog protections. You can find more details in Section 5.2.16 of the TRM.

The bq76952 includes a built-in high-side FET driver, so high-side FETs with the bq76952 are easy to implement.
