Product Summary

The SI4431DY-TI is a P-Channel Logic Level PowerTrench MOSFET. It is produced using Fairchild Semiconductor’s advanced PowerTrench process that has been especially tailored to minimize on-state resistance and yet maintain superior switching performance. The SI4431DY-TI is well suited for low voltage and battery powered applications where low in-line power loss and fast switching are required. The SI4431DY-TI is used in DC/DC converter, Load switch, Motor Drive.
