Hi,

The Power Monitor component uses the internal ADC to measure the voltage inputs. It compares the results against the OV/UV thresholds.

Advantage: High resolution (12-bits)

Disadvantage: Slow scanning rate. Around 150 us per rail.

The Voltage Fault Detector uses a comparator voltage window.

Advantage: Faster scanning rate and response time. Around 4 us per rail.

Disadvantage: Low resolution (8-bits)
