NCP334 Datasheet, PDF (1/10 Pages) ON Semiconductor – 2A Ultra-Small Controlled Load Switch with Auto-Discharge Path

NCP334, NCP335
2A Ultra-Small Controlled
Load Switch with
Auto-Discharge Path
The NCP334 and NCP335 are 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 rail in the NCP335.
Proposed in wide input voltage range from 1.2 V to 5.5 V, and a very
small 0.96 x 0.96 mm WLCSP4, 0.5 mm pitch.
Features
• 1.2 V – 5.5 V Operating Range
