BQ79631-Q1: BQ79631-Q1

Part Number: BQ79631-Q1

Tool/software:

Hi Team

We are trying to sense from GPIO1 of BQ79631- Q1 ic.

We found that GPIO is not able to read voltage below 45 mV. 

Is there any way of measuring voltage below 45 mV by this GPIO?

Thanks and regards

    Hi Ramachandra Bhosale,

    Our recommended voltages for the GPIO inputs are between 0.2 and 4.8V. Our accurracies are specified only down to 0.080 V. We do not guarantee any accuracy as you have found for below 45 mV. 

    There is no information in the datasheet regarding measuring voltages below 45 mV and so I do not believe there is a method for this. 

    Best Regads,
