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.
