BQ79731-Q1: Current sense setting of BQ79731-Q1 GUI

Part Number: BQ79731-Q1

Hi team,

I'm using BQ79731-Q1 GUI to test the current detect function.

And I find there is a current sense setting in the GUI.

Could you please tell me what the meaning of CS_DR and how to choose the CS_DR and the LPF_CS?

Thanks & Best Regards,

Brian

    HI Brian,

    These two settings are to configure CS ADCs operation controls. Before starting the CS ADCs sampling, please configure the proper settings desired.

    The CS_DR is to configure the CS ADC continuous mode refresh rate( decimation ratio), and the LPF_CS is to select the post CS ADC first order digital low pass filter cut off frequency for current measurement.
