AO4449
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4449 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
AO4449 is Pb-free (meets ROHS & Sony 259
specifications).
