Infineon Technologies AG Power Load Sw, High Side, -30 To 85Deg C; Power Load Switch Type Infineon ISP452HUMA1

The ISP452HUMA1 is a high-side power switch designed for industrial applications, featuring an N-channel vertical power FET with integrated protection functions. It supports a maximum supply voltage of 40 V and is capable of handling resistive, inductive, and capacitive loads, making it suitable for microcontroller-compatible power switching in 12 V DC grounded systems. Key protective features include short-circuit protection, overtemperature protection with hysteresis, overload protection, overvoltage protection, and undervoltage shutdown. The device also incorporates electrostatic discharge (ESD) protection and reverse battery protection. The ISP452HUMA1 is packaged in a PG-SOT 223 format, ensuring a compact footprint for integration into various designs. With a maximum load current that is internally limited and a typical on-state resistance of 200 m,Ѷ at 25 °C, this power switch is designed to replace electromechanical relays and discrete circuits, providing a reliable solution for power management in demanding environments.
