FDR8521L
P-Channel MOSFET With Gate Driver For Load Switch Application
General Description
This device is designed for configuration as a load switch
and is particularly suited for power management in por-
table battery powered electronic equipment. Designed to
operate from 3V to 20V input and supply up to 2.9A, the
device features a small N-Channel MOSFET (Q1) together
with a large P-Channel Power MOSFET (Q2) in a single
SO-8 package.
