AO4944
Dual N-Channel Enhancement Mode Field Effect Transistor
SRFET ^TM
General Description
Features
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).
V_DS (V) = 30V
I_D = 8.6A
(V _GS = 10V)
R_DS(ON) < 16mΩ (V_GS = 10V)
R_DS(ON) < 20mΩ (V_GS = 4.5V)
