General Description
The AO4421 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
AO4412 is Pb-free (meets ROHS & Sony 259
specifications). AO4421L is a Green Product
ordering option. AO4421 and AO4421L are
electrically identical.
