Features

Typical connection with reverse battery protection

Description

 Up to 30Khz PWM switching capability

 Charge pump for DC operation

 Active di/dt control to reduce EMI

 Load current feedback

 Short-circuit protection

 Programmable over current shutdown

 Over temperature shutdown

 Diagnostic feedback

 Under voltage shutdown

 Gnd, IN and bootstrap pin loss protection

 E.S.D protection

 Low power mode

 Lead-free, RoHS compliant

Ifbk pin. The over-current shutdown is programmable from 5A to 50A. Over-current, over-temperature latch OFF the power

switch, providing a digital diagnostic status on the input pin. In sleep mode, the device consumes typically less then 1uA.

Further integrated protections such as ESD and GND disconnect protection guarantee safe operation in harsh conditions of

the automotive environment.

The AUIR3330S 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
