AO4443
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4443 uses advanced trench technology to
provide excellent R_DS(ON), and ultra-low low gate
charge. This device is suitable for use as a load
switch or in PWM applications. Standard Product
AO4443 is Pb-free (meets ROHS & Sony 259
specifications). AO4443L is a Green Product
ordering option. AO4443 and AO4443L are
electrically identical.
Features
