Infineon BTS50085 Smart High Side Power Switch 58V 90A TO-220-7

The Infineon BTS50085 Smart High Side Power Switch is a robust, high current power switch engineered for demanding automotive and industrial applications. Housed in a compact 7-pin TO-220 package, this device integrates an N-channel vertical power FET with a charge pump, current-controlled input, and diagnostic feedback with load current sense, all built using advanced SMART SIPMOS chip-on-chip technology.

Designed to handle up to 48VDC grounded loads, this switch is ideal for applications with high inrush currents such as lamps and motors, as well as all types of resistive and inductive loads. It effectively replaces electromechanical relays, fuses, and discrete circuits, offering enhanced reliability and performance.
