FDC6901L
Integrated Load Switch
General Description
This device is particularly suited for compact power
management. In portabl e electronic equipm ent 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 cont rol 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.
