LTC4421 - High Power Prioritized PowerPath Controller

Datasheet Summary

Description

The LTC®4421 connects one of two input supplies to a common output based on user-defined priority and validity.

By definition, the supply connected to V1 is the higher priority supply, although this can be changed dynamically.

Features

  • n 0V to 36V Wide Operating Range (60V Tolerant) n Drives Large External N-Channel MOSFETs for High Output Current.
