Voltage Fault Detector (VFD)

The Voltage Fault Detector component provides a simple way to monitor up to 32 voltage inputs against user-defined over and under voltage limits without using the ADC and without having to write any firmware. The component simply outputs a good/bad status result (“power good” or pgood[x]) for each voltage being monitored.

The component operates entirely in hardware without any intervention from PSoC™’s CPU core resulting in known, fixed fault detection latency.

Note: This component supports PSoC™ 3 and PSoC™ 5LP devices only.
