This document is about the technical data of PROFET® BTS 442 E2, which is a high-end power switch with overload protection, current limitation, short circuit protection, thermal shutdown, overvoltage protection and other functions. It is suitable for 12V and 24V DC grounded loads and can replace electromechanical relays and discrete circuits.
The PROFET® BTS442E2 is a smart high‑side power switch with integrated overload, over‑voltage, short‑circuit, thermal shutdown, and reverse‑battery protection. It is designed for uC‑compatible power switching of resistive, inductive, and capacitive loads in 12 V and 24 V systems, replacing electromechanical relays.
The document lists pin assignments, maximum ratings, electrical characteristics, and detailed protection functions. It also includes the truth table, status output behavior, and package/ordering information for the TO‑220AB/5 version.
