Overvoltage Protection Circuit

The voltage protection circuit on the CSK carrier card protects the board from overvoltage, undervoltage,
transient-voltage, and reverse-voltage input cases. The safe operation input-voltage range is 4.5 V to 5.25
V. Any voltage that is not in this range is considered a fault and the voltage protection circuit isolates the
board from this input. LED LD2 indicates if the DC input applied to the board is within a safe input range.

Figure 6-4

shows the overvoltage protection circuit.
