Overview
The NCP335FCT2G, produced by onsemi, is a high-side P-channel MOSFET power distribution switch designed to optimize battery life and device autonomy in portable electronics. This component is part of the NCP334 and NCP335 series, which feature low RDS(on) and an external logic pin for enabling the power switch. The NCP335FCT2G includes an auto-discharge path, which helps eliminate residual voltages on the output rail when the switch is disabled.
