BQ76942: Production tool and process

Part Number: BQ76942

To whom it may concern:

We are using bq76942 for a new design, and need some help on the below quesitons:

1. Is there any production software available, such as BQ tester or BQ production, that can be used in mass production?

2. What is the normal production process for this IC? The OTP need to be programmed between 10V to 12V, so for high voltage battery 6S+ (15V+), how is the normal practice? Program the OTP first then run the PCBA level test? For the other ICs, we always use the same step to program the IC and test the PCBA.

Thank you!

  • Hi Chen,

    There is no tool like BQ Production for this device.

    Most users will use the host to configure the registers when coming out of Shutdown. OTP is another option for applications that need specific settings to be set at power-up, but this requires an additional production step because the device needs to be supplied with 10-12V, so cells cannot be connected yet. Yes, it can be programmed just before doing your PCBA level test.

    Best regards,

    Matt
