This document introduces the features and characteristics of BTS 725 L1 smart two-channel high-side power switch.
The Siemens BTS 725 L1 is a smart two‑channel high‑side power switch with integrated protection functions such as over‑voltage, over‑current, thermal shutdown, and reverse‑battery protection. It features CMOS‑compatible inputs, open‑drain diagnostic outputs, and is designed for 12 V DC grounded loads, replacing electromechanical relays.
The document provides detailed pin definitions, maximum ratings, electrical characteristics, protection functions, and package information, enabling designers to integrate the device into PCB layouts and control circuits.
