Infineon High Side Power Switch SOT-223-4 Single Output 40V

The Infineon Smart Power High Side Switch utilises advanced SIPMOS technology to deliver reliable performance through an integrated vertical power FET. Designed with embedded protection and diagnostic functions, this single-output switch ensures robust operation in demanding environments.

Comprehensive protection is a key feature of this device. It includes short-circuit, overload, overvoltage, and input protection to safeguard the circuit. Additionally, it offers over-temperature protection with hysteresis, under-voltage shutdown, and electrostatic discharge (ESD) protection. For automotive reliability, it incorporates reverse battery protection and a clamp for negative output voltage when switching inductive loads. The maximum current is internally limited, and a thermal shutdown function with automatic restart further enhances operational safety.

This high side power switch is AEC-Q100 qualified, confirming its suitability for automotive applications. It is also classified as a Green Product and features very low standby current, optimising energy efficiency. The active high on/enable input polarity facilitates straightforward integration into your circuit designs.
