Infineon Technologies AG Power - Smart power switches - High-side switches - PROFET™ Wire Guard 12V | Automotive smart high-side switch - BTG7003A-1EPW BTG7003A-1EPW

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. Summary of Features High-side switch with embedded protection Sequential diagnosis for status readout Selectable integrated I²t protection Operating current < 60 µA during parking IDL pin for microcontroller wake-up Adjustable overcurrent protection threshold Capacitive load switching mode Reverse ON for reverse polarity Inverse current condition capable Benefits Precise wire protection Fast failure isolation to power supply Precise application diagnostics Dynamic load control during parking Automatic Idle mode at ~ 50 µA Fast, safe charging of big capacitors pin and footprint compatibility ISO 26262-compliant Potential Applications Replaces electromechanical relays, fuses and discrete circuits Protection of wire harness and system supply Main switch for ECU power supplies Switch for active power supplies in key-off mode Suitable for resistive, inductive and capacitive loads up to 15.7 A Access to ISO 26262-ready documentation Please register for myinfineon.com with your company e-mail address Please get in touch with your respective Distribution or Sales contact to request the elevation of your myInfineon account to partner status; this is required for access to our MyICP portal Designers who used this product also designed with BTS70020-1ESP | PROFET™ +2 12V | automotive smart high-side switch BTS7030-2EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7006-1EPP | PROFET™ +2 12V | automotive smart high-side switch BTS7020-2EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7002-1EPP | PROFET™ +2 12V | automotive smart high-side switch BTN9970LV | MOTIX™ single half-bridge ICs for BDC motors BTS7200-4EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7040-1EPA | PROFET™ +2 12V | automotive smart high-side switch BTS70012-1ESP | PROFET™ +2 12V | automotive smart high-side switch 2ED2410-EM | Automotive gate driver ICs BTS7012-1EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7200-2EPA | PROFET™ +2 12V | automotive smart high-side switch TLE92104-232QX | MOTIX™ multi MOSFET gate driver ICs for BDC motors BTS70015-1ESP | PROFET™ +2 12V | automotive smart high-side switch BTS7040-2EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7120-2EPA | PROFET™ +2 12V | automotive smart high-side switch BTS70020-1ESP | PROFET™ +2 12V | automotive smart high-side switch BTS7030-2EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7006-1EPP | PROFET™ +2 12V | automotive smart high-side switch BTS7020-2EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7002-1EPP | PROFET™ +2 12V | automotive smart high-side switch BTN9970LV | MOTIX™ single half-bridge ICs for BDC motors BTS7200-4EPA | PROFET™ +2 12V | automotive smart high-side switch BTS7040-1EPA | PROFET™ +2 12V | automotive smart high-side switch 1 2 3 4
