AO4805 Datasheet, PDF (1/6 Pages) Alpha & Omega Semiconductors – Dual P-Channel Enhancement Mode Field Effect Transistor

AO4805
Dual P-Channel Enhancement Mode Field
Effect Transistor
General Description
The AO4805 uses advanced trench technology to provide excellent R_{DS(ON), and ultra-low low gate}
charge with a 25V gate rating. This device is suitable for use as a load switch or in PWM applications.
