BQ76907: OTP configuration

Reshma Tomy
Prodigy 30 points
Part Number: BQ76907

Tool/software:

We need to develop a customized OTP configuration and program it into the BQ module. However, I haven't been able to locate any documentation that provides guidance on developing and programming the OTP memory for this module.

Could you please provide some insights or resources on this?

I already checked below documents

  1. https://www.ti.com/lit/pdf/sluaam4
  2. https://www.ti.com/lit/pdf/sluucj0

I would also like to know how the OTP digital signature check works. Can host MCU access the digital signature? What does Internal Factory Trim Diagnostic Protection check for?

    Hi Reshma,

    This part does not include user programmable OTP.

    The device stores a signature used to detect bit errors in the OTP memory on startup. The host is not able to access the digital signature. The internal factory trim diagnostic checks for a failure in the memory.
