This is a power switch with negative voltage clamping, short circuit protection, overcurrent protection, thermal shutdown, diagnostic feedback, open load detection, CMOS compatible input, electrostatic discharge (ESD) protection, power supply failure protection, overvoltage protection, etc. It is suitable for 12V and 24V DC grounded loads and can replace electromechanical relays and discrete circuits.
The PROFET® BTS 432 E2 is a smart high‑side power switch with built‑in protection functions such as load‑dump, reverse‑battery, short‑circuit, over‑ and undervoltage shutdown, and diagnostic feedback. It is designed for 12 V and 24 V DC grounded loads and can replace electromechanical relays in resistive, inductive, and capacitive applications.
The document provides pin definitions, maximum ratings, electrical characteristics, protection functions, and package information for the TO‑220AB/5 version. It also includes typical application notes and reference diagrams for designers integrating the device into their circuits.
