LTC4417 - Prioritized PowerPath Controller

General Description

The LTC®4417 connects one of three valid power supplies to a common output based on priority.

Priority is defined by pin assignment, with V1 assigned the highest priority and V3 the lowest priority.

Key Features

  • n Selects Highest Priority Supply from Three Inputs n Blocks Reverse and Cross Conduction Currents n Wide Operating Voltage Range: 2.5V to 36V n.
  • 42V Protection Against Reverse Battery Connection n Fast Switchover Minimizes Output Voltage Droop n Low 28µA Operating Current n.
