Infineon AUIPS7221RTRL: The High-Current Guardian for Automotive and Industrial Loads
In the demanding worlds of automotive electronics and industrial automation, robust and intelligent power management is non-negotiable. The Infineon AUIPS7221RTRL stands out as a premier high-side intelligent power switch, engineered to deliver exceptional reliability and protection for controlling heavy inductive and resistive loads.
This device is designed to seamlessly drive loads up to 170A inrush current, making it an ideal solution for challenging applications such as solenoids, valves, motors, and lamp driving. Its integration of a low-RDS(on) N-channel MOSFET ensures minimal power dissipation, enhancing overall system efficiency and thermal performance.

A key strength of the AUIPS7221RTRL lies in its comprehensive suite of embedded protection features. It provides robust safeguards against over-current conditions, electrostatic discharge (ESD), over-temperature shutdown, and inductive load demagnetization. Crucially, it includes active current limiting and diagnostic feedback, allowing a microcontroller to monitor the output status and detect fault conditions like open-load or short-circuit to ground or battery. This intelligence enables predictive maintenance and enhances system safety.
Housed in a compact, surface-mount TO-263 package, the device offers excellent power density. Its automotive-grade qualification (AEC-Q100) ensures it meets the stringent requirements for reliability and performance in the harsh under-hood environments of vehicles, from passenger cars to heavy-duty trucks.
ICGOOODFIND: The Infineon AUIPS7221RTRL is an integrated, high-current, and intelligent power switch that combines brute strength with smart protection. It simplifies design, boosts reliability, and provides critical diagnostics, making it a top-tier choice for controlling high-power loads in the most demanding automotive and industrial systems.
