Part Number: BQ79731Q1EVM-060
Tool/software:
Dear everyone:
When we recently used the BQ79731 chip, we found that when the VF pin voltage is 0V(measured with a 4-bit semi-multimeter), the software will read 36mV voltage. However, the GPIO pin does not have this problem when used as a voltage acquisition. May I ask what causes this? In addition, when the voltage of VF pin is close to 0V, can the sampling accuracy reach 0.1mv
