AO4803
Dual P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4803 uses advanced trench technology to
provide excellent R_DS(ON) with low gate charge. This
device is suitable for use as a load switch or in PWM
applications. Standard Product AO4803 is Pb-free
(meets ROHS & Sony 259 specifications). AO4803L
is a Green Product ordering option. AO4803 and
AO4803L are electrically identical.
Features
