Description
The AUIR33402S 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 and 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.
Further integrated protections such as ESD, GND and Cboot
disconnect protection guarantee safe operation in harsh
conditions of the automotive environment.
