UT4232
Preliminary
Power MOSFET
N-CHANNEL ENHANCEMENT
MODE POWER MOSFET

DESCRIPTION
The UT4232 uses UTC advanced technology to provide
excellent RDS(ON), low gate charge and to be operated with low gate
voltages. This device is suitable for applications, such as high-side
DC/DC conversion, notebook and sever.

