General Description

Pin Name Pin Number EN A1 IN B1, C1 VBIAS D1 GATE A2 OUT B2, C2 GND D2 Type INPUT POWER POWER I

Overview

NCP458R, NCP459 4 A Single Load Switch for Low Voltage Rail The NCP458R and NCP459 are power load switch with very low Ron NMOSFET controlled by external logic pin, allowing optimization of battery life, and portable device autonomy.

Indeed, thanks to a best in class current consumption optimization with NMOS structure, leakage currents are drastically decreased.

Offering optimized leakages isolation on the ICs connected on the battery.
