NCP434FCT2G Datasheet, PDF (1/10 Pages) ON Semiconductor – 2A Ultra-Small Controlled Load Switch with

NCP434, NCP435
2A Ultra-Small Controlled
Load Switch with
Auto-Discharge Path
The NCP434 and NCP435 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 (NCP435 only).
Available in wide input voltage range from 1.0 V to 4.0 V, and a very
small 0.96 x 0.96 mm WLCSP4, 0.5 mm pitch.
Features
• 1 V − 3.6 V Operating Range
• 29 mW P MOSFET at 3.3 V
• DC current up to 2 A
• Output Auto−discharge (NCP435)
• Active high EN pin
• WLCSP4 0.96 x 0.96 mm
• These are Pb−Free Devices
Typical Applications
• Mobile Phones
• Tablets
• Digital Cameras
• GPS
• Portable Devices
