NCP439
2A Very Low Ron Switches
at Low Vin Voltage
The NCP439 is a very low Ron MOSFET controlled by external
logic pin, allowing optimization of battery life, and portable device
autonomy.
This load switch is a best in class in term of RDS(on) optimization at
low VIN voltage.
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.
Proposed in wide input voltage range from 1.0 V to 3.6 V, and a very
small 0.96 x 0.96 mm WLCSP4, 0.5 mm pitch.
Features
• 1 V – 3.6 V Operating Range
• 37 mW P MOSFET at 1.8 V
• DC Current Up to 2 A
• Output Auto−Discharge
• Active High EN Pin
• WLCSP4 0.96 x 0.96 mm
• This is a Pb−Free Device
Typical Applications
• Mobile Phones
• Tablets
• Digital Cameras
• GPS
• Portable Devices
