WPM9435 P-Channel Enhancement Mode MOSFET www.willsemi.com escription The WPM9435 is the P-Channel logic enhancement mode power field effect transistors are produced using high cell density, MOS trench technology. This high density process is especially tailored to minimize on-state resistance. These devices are particularly suited for low voltage application, notebook computer power management and other battery powered circuits where high-side switching. Features -3V/-5A,RS(ON)= 36m@VGS=- V -3V/-4A,RS(ON)= 53m@VGS=-4.5V Super high density cell design for extremely low RS (ON) Exceptional on-resistance and maximum C current capability SOP 8P package design Application S S S G Power Management in Note book Portable Equipment Battery Powered System C/C Converter Load Switch WPM9435 YYWW YYWW = ate Code WPM9435= Specific evice Code Order information WPM9435-8/TR SOP-8P 25Tape&Reel http://www.willsemi.com Page /29 Rev.3
