Overview
The NCP337FCT2GEVB, 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 NCP336 and NCP337 series, which feature very low on-resistance (Rdson) and an auto-discharge path to eliminate residual voltages on the output rail. The NCP337 is particularly useful in applications requiring efficient power management and minimal leakage currents.
