AO4404
N-Channel Enhancement Mode Field
Effect Transistor
General Description
The AO4404 uses advanced trench technology to provide excellent RDS(ON) , low gate charge and
operation with gate voltages as low as 2.5V. This device is suitable for use as a load switch or in
PWM applications. The source leads are separated to allow a Kelvin connection to the source, which
may be used to bypass the source inductance.
