General Description
This P-Channel 2.5V specified MOSFET is produced
using Fairchild's advanced PowerTrench process that
has been especially tailored to minimize on-state
resistance and yet maintain low gate charge for
superior switching performance.
These devices have been designed to offer exceptional
power dissipation in a very small footprint for
applications where the larger packages are impractical.
Applications
• Load switch
• Battery protection
• Power management
