Infineon Technologies PROFET™ wire guard

The single-channel high-side power switches of the PROFET™ Wire Guard family are designed for wire protection in power distribution systems of modern automotive E/E architectures. They are equipped with integrated I²t wire protection and enhanced diagnostic capabilities. Their adjustable overcurrent protection threshold ensures fast failure isolation towards power supplies and the automatic idle mode reduces the current consumption to ~50 µA (typ.) during parking.

Key features

• Selectable, integrated I²t wire protection
• Sequential diagnosis for status readout
