3.2.1 Over Voltage and Under Voltage Protection Circuit
The voltage protection circuit on the EVM protects the board from overvoltage, under voltage and transient
voltage input cases. The safe operation input voltage range is 6 V to 28 V. A fault indication and power good
LEDs are provided to indicate the power status.
