SPN4946
N-Channel Enhancement Mode MOSFET
DESCRIPTION
The SPN4946 is the Dual N-Channel logic enhancement
mode power field effect transistors are produced using
high cell density , DMOS 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 .
