BTG7003A-1EPW | 12 V | 3.6 mΩ | 15.7 A | integrated I²t wire protection| automatic Idle mode | 1 channel smart high-side power switch | analog current sense, sequential diagnosis | PG-TSDSO-14 | ISO 26262-compliant | PROFET™ Wire Guard 12V

Overview

The single-channel high-side power switch BTG7003A-1EPW, member of the PROFET™ Wire Guard family, is designed for wire protection in modern automotive E/E architectures. It is equipped with integrated I²t wire protection, and enhanced diagnostic capabilities. Its adjustable overcurrent protection threshold ensures fast failure isolation towards power supplies and the automatic idle mode reduces the current consumption to ~ 50 µA during parking.
