NCP436

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 http://onsemi.com MARKING DIAGRAM WLCSP6 CASE 567FH XXX AYW G A = Assembly Location Y = Year W = Work Week G = Pb−Free Package PIN DIAGRAM A OUT IN B OUT IN C GND EN (Top View) ORDERING INFORMATION See detailed ordering, marking and shipping information in the package dimensions section on page 6 of this data sheet.
