Overview
distribution switch designed to isolate ICs connected on the
battery in order to save energy. The part can be turned on,
with a wide range of battery from 1.2 V to 5.5 V.
Enable Input
pin is tied low (disable), forcing P MOS switch off.
1.2 V and EN forced to high level.
The NCP337 is a high side P channel MOSFET power
Enable pin is an active high. The path is opened when EN
The IN/OUT path is activated with a minimum of Vin of

long as EN pin is set at low level and Vin > 1.2 V.
Nmosfet, the typical value is set at 70 W.
Cin and Cout Capacitors
close as possible the part to for stability improvement.
NMOS FET is placed between the output pin and GND,
The auto−discharge is activated when EN pin is set to low
The discharge path (Pull down NMOS) stays activated as
In order to limit the current across the internal discharge
