BTS 452 R Smart Power High-Side-Switch is a power switch with overload protection, current limitation, short circuit protection, thermal shutdown, overvoltage protection (including load dump) for 12 V, 24 V and 42 V DC applications.
The BTS452R is an N‑channel vertical power FET with a charge pump and CMOS‑compatible input, designed for high‑side switching in 12‑42 V DC applications. It integrates multiple protection features such as overload, over‑voltage, short‑circuit, reverse‑battery, and thermal shutdown, making it suitable for replacing electromechanical relays.
The document details the device’s pin configuration, maximum ratings, electrical characteristics, and package information. It also includes timing diagrams for turn‑on/off behavior and describes the status output signals used for diagnostic feedback.
