This document describes the features and characteristics of the PROFET® BTS 840 S2 (model) product from Infineon Technologies. It includes dual channels, low on-state resistance, proportional load current sense, and various protective functions. The product is suitable for use with 12V and 24V grounded loads and can replace electromechanical relays, fuses, and discrete circuits.
The Infineon BTS 840 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 12 V and 24 V grounded loads, supporting resistive, inductive and capacitive loads, and replaces electromechanical relays and fuses.
The device offers CMOS‑compatible inputs, overload, over‑ and undervoltage shutdown, thermal protection, reverse‑battery protection and ESD protection. Detailed electrical characteristics, thermal data, pin definitions and ordering information are provided for designers.
| Overvoltage shutdown voltage | 34 – 43 V |
