Smart High Side Power Switch

Low and high side internal high current clamps when driving inductive loads.

Smart high side power switch. They belong to an expanding family designed to control protect and diagnose various types of loads with enhanced precision in bcm ecu or junction boxes. With power on delay time of less than 60µs the ips160hf and ips161hf single channel high side switches satisfy standardized requirements for interface types c and d in safety integrity level sil class 3 applications. In addition several protection features are integrated. The device enlarges st s family of galvanic isolated high side switches.

Profet stands for protected mosfet and gathers all high side switches whether they are automotive qualified or designed for the needs of industrial applications. A power good output indicates the status of the process side power supply. The bts7010 2epa is a smart high side power switch 10mω dual channel providing protection functions and diagnosis the device is integrated in smart7 technology. This requires both a robust low on resistance power switch and accurate analog circuitry for diagnostic protection and control functions.

Profet intelligent power switches consist of dmos power transistor and cmos logic circuitry for complete built in protection. For example short circuit protection can protect the mosfet if a short to ground battery occurs. High side switches can safely drive high currents into complex resistive inductive and capacitive grounded loads in compliance with the harsh automotive environment.

Profet protected field effect transistors is our high side smart power switch brand. With our switch portfolio you can find a protection solution for your inductive capacitive and resistive loads ensuring your design is scalable and robust. It consists of a mosfet a gate driver with charge pump and multiple protection and diagnosis features. With a supply voltage range up to 60 v these intelligent power switches are capable of safely driving complex resistive capacitive and inductive loads with one side.

The profet 12v and 24v families are infineon s solution for power switch ics. With adjustable current limit high accuracy current sense and a wide range of rdsons our smart high side switches provide the optimal solution for your specific use case. The galvanic isolated octal high side smart power switch enhances diagnostics and system management by providing a 20 mhz spi port allowing both per channel over temperature signalization and efficient daisy chaining of multiple devices.
