• Manufacturer Part Number: NCP335FCT2G
• Description: Power Switch ICs - Power Distribution
• Manufacturer: ON Semiconductor

Overview
power distribution switch designed to isolate ICs connected
on the battery in order to save energy. The part can be turned
on, with a range of battery from 1.2 V to 5.5 V.
Enable Input

1.2V and EN forced to high level.
Auto Discharge (NCP335 Only)
in order to discharge the application capacitor connected on
OUT pin.
The NCP334 – NCP335 are high side P channel MOSFET
Enable pin is an active high. The path is opened when EN
