PROFET BTS 723 GW is a high-side power switch produced by Infineon. It has two parallel channels and a switch resistance of 53mΩ. The rated load current is 4.2A. It integrates many protection functions, such as short circuit protection, overload protection, current limitation, thermal shutdown, undervoltage protection, etc.
The BTS 723 GW is a smart high‑side power switch from Infineon, featuring two independent channels that can handle up to 42 V grounded loads. It integrates a charge pump, CMOS‑compatible input, and diagnostic feedback, making it suitable for resistive, inductive, and capacitive loads and allowing replacement of electromechanical relays and fuses.
Key features include integrated protection functions (short‑circuit, overload, current‑limit, thermal shutdown, over‑voltage, reverse‑battery, and ESD), on‑state resistance as low as 53 mΩ in parallel mode, and a compact P‑DSO‑14 package. The datasheet details pin assignments, electrical and thermal characteristics, and ordering information.
