Hi,

How this analyzer measure voltage and current? Is there any shunt-resistor on bus VBUS?

Is there any schematic file?

Thanks

Hi,

We have a series resistor on the VBUS pin and the voltage drop is measured by using a current sense amplifier. The VBUS is measured using a resistive divider on a VBUS monitoring GPIO.

Unfortunately, we wont be able to share the schematic file.

Best Regards,

Sananya
