Fairchild FDC6901L Integrated load switch Datasheet

FDC6901L
Integrated Load Switch
General Description
Features
This device is particularly suited for compact power
management. In portable electronic equipment where 2.5V
to 6V input capability is needed. This load switch integrates
a Slew Rate Control Driver that drives a P-Channel Power
MOSFET in one tiny SuperSOT-6 package. The
integrated slew rate control driver is specifically designed
to control the turn on of the P-Channel MOSFET in order to
limit the inrush current in battery switching applications with
high capacitance loads. For turn-off, the IC pulls the
MOSFET gate up quickly.
