NCP336 Datasheet, PDF (1/9 Pages) ON Semiconductor – 3 A Ultra-Small Controlled Load Switch

NCP336, NCP337
3 A Ultra-Small Controlled
Load Switch with
Auto-Discharge Path
Description
The NCP336 and NCP337 are very low Ron MOSFET controlled
by external logic pin, allowing optimization of battery life, and
portable device autonomy.
Indeed, thanks 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 NCP337 part only.
Proposed in a wide input voltage range from 1.2 V to 5.5 V, in a
small 1 x 1.5 mm WLCSP6, pitch 0.5 mm.
