NCP436 Datasheet, PDF (1/7 Pages) ON Semiconductor – 3A Ultra-Small Controlled Load Switch

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.
Features
• 1.0 V − 3.6 V Operating Range
• 20 mW P MOSFET at 3.6 V
• DC Current Up to 3 A
• Output Auto−discharge
• Active High EN Pin
• WLCSP6 1 x 1.5 mm
• These are Pb−Free Devices
Typical Applications
• Mobile Phones
• Tablets
• Digital Cameras
• GPS
• Portable Devices
