Integrated Load Switch
General Description
This device is particularly suited for compact power
management in portable electronic equipment where
2.5V to 8V input and 0.8A output current capability are
needed. This load switch integrates a small N-Channel
power MOSFET (Q1) that drives a large P-Channel
power MOSFET (Q2) in one tiny SC70-6 package.
Applications
• Power management
• Load switch
