Disruptive Reverse Polarity Protection

Motivation

  • Reverse battery causes high current which damage or even destroy circuits
  • RPP is a mandatory function implemented in every ECU

Goals

  • Integrated RPP solution
  • Reverse current elemination
  • Reverse voltage blocking
  • Lower system costs than recent solutions
  • Lower voltage drop than recent solutions
  • Consideration of ISO standards

Applications

  • Automotive application, especially:
  • High side / low side switch
  • Linear Voltage Regulators
