Description

The PMP10737 is a reference design that provides protection from reverse polarity and overvoltage using discrete components. The Input voltage range is between 7V to 35V with OVP at 25V. The LM74610 is used for battery reverse protection, which utilizes a charge pump to drive an N-channel FET to provide a resistive path for the bypass current to flow.

Features
  • Reverse Protection through Smart diode
  • Overvoltage Protection using Discrete Components
  • Extremely Low Power Dissipation
  • No Quiescent Current
