AO4601
Complementary Enhancement Mode Field Effect Transistor
General Description
Features
n-channel p-channel
The AO4601 uses advanced trench technology
MOSFETs to provide excellent R
DS(ON)
and low
gate charge. The complementary MOSFETs may
be used to form a level shifted high side switch,
and for a host of other applications. Standard
Product AO4601 is Pb-free (meets ROHS & Sony
259 specifications). AO4601L is a Green Product
