NCP436, NCP437
3A Ultra-Small Controlled
Load Switch with
Auto-Discharge Path
The NCP436 and NCP437 are 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.
Output discharge path is also embedded to eliminate residual
voltages on the output rail for the NCP437 part only.
Proposed in a wide input voltage range from 1.0 V to 3.6 V, in a
small 1 x 1.5 mm WLCSP6, pitch 0.5 mm.

FUNCTIONAL DESCRIPTION
Overview
The NCP437 is a high side P channel MOSFET power
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 1.0 V to 3.6 V.
Enable Input
Enable pin is an active high. The path is opened when EN
pin is tied low (disable), forcing P MOS switch off.
The IN/OUT path is activated with a minimum of VIN of
1.2 V and EN forced to high level.
The auto−discharge is activated when EN pin is set to low
level (disable state).
The discharge path (Pull down NMOS) stays activated as
long as EN pin is set at low level and VIN > 1.2 V.
In order to limit the current across the internal discharge
N−MOSFET, the typical value is set at 65 W.
CIN and COUT Capacitors
IN and OUT, 1 mF, at least, capacitors must be placed as
close as possible the part to for stability improvement.
Auto Discharge
NMOS FET is placed between the output pin and GND,
in order to discharge the application capacitor connected on
OUT pin.
