AO4437
P-Channel Enhancement Mode Field Effect Transistor
General Description
The AO4437 uses advanced trench technology to provide
excellent R_DS(ON), low gate charge and operation with gate
voltages as low as 1.8V. This device is suitable for use as a
load switch or in PWM applications. It is ESD protected.
Standard Product AO4437 is Pb-free (meets ROHS & Sony
259 specifications). AO4437L is a Green Product ordering
option. AO4437 and AO4437L are electrically identical.
