This data sheet is for the BTS550P product. It mainly introduces the features and characteristics of the product, such as reverse battery protection, overload protection, current limiting, short circuit protection, overtemperature protection, overvoltage protection, output negative voltage clamping, fast deenergizing of inductive loads, low ohmic reverse current operation, diagnostic feedback with load current sense, open load detection, Vbb loss protection, and electrostatic discharge protection.
The BTS550P is a smart high‑side power switch with integrated protection functions such as reverse‑battery, overload, short‑circuit, over‑temperature, over‑voltage and ESD protection. It is designed for 12 V and 24 V DC grounded loads, especially those with high inrush currents like lamps and motors, and can replace electromechanical relays and fuses.
The data sheet details electrical characteristics, thermal data, pin configuration, maximum ratings, and diagnostic features including a current‑sense output. It also lists ordering codes, package dimensions, and application notes for parallel operation and inductive load switching.
