General Description
SRFET
TM
The AO4944 uses advanced trench
technology with a monolithically integrated Schottky
diode to provide excellent R
DS(ON)
and low gate
charge. This device is suitable for use as a low and
high side switch in SMPS and general purpose
applications. Standard product
AO4944 is Pb-free
(meets ROHS & Sony 259 specifications)
