Infineon BTS441R Smart Highside Power Switch Datasheet
The BTS441R is a smart high‑side power switch that integrates a charge‑pump N‑channel MOSFET with embedded protection functions. It is designed for uC‑compatible power switching in 5 V, 12 V and 24 V DC applications and can handle resistive, inductive and capacitive loads, including those with high inrush currents such as lamps.
The device offers a range of built‑in protections—short‑circuit, current‑limit, overload, thermal shutdown, over‑voltage, reverse‑battery, loss‑of‑ground and ESD—plus diagnostic feedback via an open‑drain status output. Detailed electrical characteristics, maximum ratings and package information are provided for PCB designers.
