The SiP4282 is a P-Channel MOSFET power switch IC designed for high-side load switching applications. The output switching transistor is a P-Channel MOSFET device that has a 140 m RDS(ON) typically to increase load switching power handling capacity. The SiP4282 is available in two different versions with turn-on and turn-off characteristics ranging from very fast to slew rate limited. In addition to a fast turn-off time of 4 s, the SiP4282-3 version offers a shutdown load discharge circuit to instantaneously turn off a load circuit when the switch is disabled.
