FDC6326L
Integrated Load Switch
General Description
This device is particularly suited for compact power
management in portable electronic equipment where 3V to
20V input and 1.8A output current capability are needed.
This load switch integrates a small N-Channel power
MOSFET (Q1) which drives a large P-Channel power
MOSFET (Q2) in one tiny SuperSOT
TM
-6 package.
