1 PROFET + Benchmark Robustness and Diagnostics in Modular Packages

2 Introduction Infineon launches its next generation of discrete smart high-side switches PROFET +. The family is designed to drive light bulbs and LEDs in the harsh automotive environment but can also be used for industrial applications. The devices provide state-of-the-art diagnostics and protection features. Their high current sense accuracy (kil) is able to diagnose even the smallest loads, such as LEDs. The very high short-circuit robustness across the whole family sets the market benchmark. Infineon is the first company to specify the short-circuit robustness of a device in the datasheet. 100k cycles SC robustness (PROFET + 1V) is a factor 00 improvement towards today s smart high-side drivers in the market. Based on the identical footprint of its packages, maximum design flexibility is provided, allowing loads and devices to be changed without major modification of the board layout.

3 Applications Overview 1V grounded high-side loads from 10A down to 0.A (permanent/channel) Qualified for automotive applications, such as lighting, body control modules, heating, energy/power distribution Capacitive loads, such as bulb lamps with high inrush currents or LEDs with low currents Resistive loads, such as heating streamer Inductive loads, such as electromagnetic valves Replacement of electromechanical relays, fuses and discrete circuits 3
