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.
