AO4459
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4459 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 AO4459 is Pb-free (meets ROHS & Sony 259
specifications). AO4459L is a Green Product ordering
option. AO4459 and AO4459L are electrically identical .
