PROFET® BTS 740 S2, Smart High-Side Power Switch, is a high-performance power switch that supports 12V and 24V grounded loads. It has overvoltage protection, short circuit protection, overload protection, current limiting, thermal shutdown, leakage protection, electrostatic discharge protection and other functions.
The PROFET® BTS 740 S2 is a dual‑channel smart high‑side power switch with integrated charge pump, diagnostic feedback and proportional load‑current sensing. It is designed for automotive and industrial applications, replacing electromechanical relays, fuses and discrete circuits for resistive, inductive and capacitive loads.
The document provides functional diagrams, pin definitions, maximum ratings, electrical and thermal characteristics, protection functions, and package information. It also includes a truth table and ordering codes for the P‑DSO‑20‑9 package.
