FDC6901L
Integrated Load Switch
Features
General Description
Three Programmable Slew Rates
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 SuperSOTTM-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.
