NCP339 3A Ultra-Small Controlled Load Switch

Pin Name Pin Number Type Description IN A2, B2 POWER Load-switch input voltage; connect a 1 mF or greater ceramic capacitor from IN to GND as close as possible to the IC. GND C1 POWER Ground connection. EN C2 INPUT Enable input, logic high turns on power switch. OUT A1, B1 OUTPUT Lo.

NCP339 3 A Ultra-Small Controlled Load Switch with Auto-Discharge Path and Reverse Current Control The NCP339 is a very low Ron MOSFET controlled by external logic pin, allowing optimization of battery life, and portable device autonomy. Indeed, due to a current consumption optimization with PMOS structure, leakage currents are eliminated by isolating connected IC on the battery when not used. Reverse blocking control is automatically engage if OUT pin voltage is higher than IN pin voltage, eli.
