BQ76952：Current calibration

Yanchi Chen

Part Number: BQ76952

Tool/software:

I'm developing a BMS larger than +-32A.
However, I don't know how to make the GUI display values greater than +-32A.
How should I set it on the GUI?

If I want to display 120A, how should I set it?

Hello Yanchi,

First, you need to calculate and choose the correct sense resistor. This is shown in Section 16.2.2 Detailed Design Procedure, Sense resistor selection, of the datasheet.

Then follow Section 2.6 Current Calibration in the BQ76x92 Calibration and OTP Programming Guide.

Best Regards,
Alexis
