AO8808
Dual N-Channel Enhancement Mode Field Effect Transistor
General Description
The AO8808 uses advanced trench technology to provide
excellent R
DS(ON)
, low gate charge and operation with gate
voltages as low as 1.8V while retaining a 12V V
GS(MAX)
rating.
This device is suitable for use as a uni-directional or bi-
directional load switch, facilitated by its common-drain
configuration.
Standard Product AO8808 is Pb-free (meets
ROHS & Sony 259 specifications). AO8808L is a Green
Product ordering option. AO8808 and AO8808L are electrically
identical.
