The AUIPS7091G from Infineon Technologies is an Automotive Qualified Five-Terminal Intelligent Power Switch IC that has been designed to provide efficient and reliable power control for a wide range of applications. It requires an input voltage of 6 – 28 V. This power switch features an output current limiter that is activated when the thermal protection circuit is triggered, thereby preventing damages to ensure that it operates within safe operating limits. It has an over-temperature protection function that turns off the device if the junction temperature exceeds the shutdown threshold. This AEC-Q100-qualified IC features a diagnostic pin that provides status feedback on short circuits, over-temperature, and open load detection, making it easy to identify any issues or problems that may occur during operation. It has double-level shifter circuitry that allows for large offsets between the logic ground and the load to provide greater flexibility and allow the device to be used in a wider range of applications.

This power switch has built-in short circuit protection, over-temperature protection, electrostatic discharge (ESD) protection, inductive load capability, and diagnostic feedback functions for ensuring safe and reliable operation during abnormal conditions. It is available in a through-hole package that measures 9.65 x 14.22 x 3.56 mm and is ideal for braking applications.
