... Integrated MOSFET These devices represent a new level of safety and integration by combining the NCP345 overvoltage protection circuit (OVP) with P−channel power MOSFET (NUS2045MN) or with P−channel power MOSFET (NUS3045MN). They are specifically designed to protect sensitive electronic circuitry from overvoltage transients and power supply faults ...
