General Description

The devices are for power MOSFET gate drivers, which

interface directly to driver the power MOSFET. There

are three high side drivers and three low side drivers to

driver six N-channel power MOSFET.

The high side driver operates up to 80 Volts. The input

logic power is from VDD, so it can easy to interface with

microcontroller.
