Package

Description

The AUIR33401S is a 7 terminals high side switch for variable

speed DC motor. It features simplify the design of the DC

motor drive with a microcontroller. The Mosfet switches the

power load proportionally to the input signal duty cycle at the

same frequency and provides a current feedback on the Ifbk

pin. The over-current shutdown is programmable from 10A to

33A. Over-current, over-temperature latch OFF the power

switch, providing a digital diagnostic status on the input pin. In

sleep mode, the device consumes less than 10uA.

D2Pak - 7 leads

Further integrated protections such as ESD, GND and Cboot

disconnect protection guarantee safe operation in harsh

conditions of the automotive environment.
