Other Parts Discussed in Thread: BQSTUDIO
Tool/software:
Using BQStudio and mentioned BQZ file, the ADC registers (VAC_ADC, VBAT_ADC< IAC_ADC, and IBAT_ADC) readings do not match actual measured values. The VAC_ADC and VBAT_ADC readings are lower by 200mV than measured with a DMM and the IAC_ADC and IBAT_ADC readings are considerably lower than measured (IAC is 215mA reading vs. 395mA measured and IBAT is 360mA reading vs. 510mA measured). It is configured for 2S battery config(JP1=open, JP2=56K). Since I haven't changed either sense resistor (input R2=0.002 ohm and battery sense R24= 0.005 ohm), what could be the problem? I did verify that the 16-bit 2's complement word matched the value (V or mA) displayed, but again the displayed value doesn't match the measured value. The chip rev is 2.
