General Description

The LTC®4412HV controls an external P-channel MOSFET to create a near ideal diode function for power switchover or load sharing.

This permits highly efficient OR’ing of multiple power sources for extended battery life and low self- heating.

When conducting, the voltage drop across the MOSFET is typically 20mV.

Key Features

  • Very Low Loss Replacement for Power Supply OR’ing Diodes.
  • 3V to 36V AC/DC Adapter Voltage Range.
  • 40°C to 125°C Operating Temperature Range.
  • Minimal External Components.
  • Automatic Switching Between DC Sources.
  • Simplifies Load Sharing with Multiple Batteries.
  • Low Quiescent Current: 11µA.
  • 2.5V to 36V Battery Voltage Range.
  • Reverse Battery Protection.
  • Drives Almost Any Size MOSFET for Wide Range of Current Requirements.
  • MOSFET Gate Pro.
