Infineon BTS824R Smart High‑Side Power Switch Datasheet
The BTS824R is a smart high‑side power switch with four parallel channels, each capable of handling high inrush currents for resistive, inductive and capacitive loads. It integrates charge‑pump MOSFETs, diagnostic feedback, and a range of protection functions such as short‑circuit, overload, thermal shutdown, over‑voltage, reverse‑battery and ESD protection.
The document provides detailed pin definitions, maximum ratings, thermal and electrical characteristics, operating parameters, and package information (P‑DSO‑20‑12). It is intended for designers who need to replace electromechanical relays or fuses with a compact, CMOS‑compatible solution.
