NCP432 Datasheet, PDF (1/7 Pages) ON Semiconductor – 1.5A Ultra-Small Controlled Load Switch with Auto-Discharge Path

NCP432, NCP433
1.5A Ultra-Small Controlled
Load Switch with
Auto-Discharge Path
The NCP432 and NCP433 are a 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’s
on the battery when not used.
Output discharge path is also embedded to eliminate residual
voltages on the output (NCP433 only).
Proposed in wide input voltage range from 1.0 V to 3.6 V, and a very
small 0.76 x 0.76 mm WLCSP4, 0.4 mm pitch.
