Either an N-channel or a P-channel MOSFET can be used for high-side reverse-battery protection. An N-channel device provides the lowest power loss topology by virtue of its low RDS(ON). However, a gate voltage greater than the battery voltage is needed to
Inadequate Device Rating: Using a protection device with an inadequate current rating for the circuit it is intended to protect can result in the device being damaged during an overcurrent event. For instance, if a lower-rated fuse or circuit breaker is used in a circuit with a consistently high current load, it may trip or blow repeatedly, leading to damage.
