MAX5973 Datasheet (Maxim Integrated Products) - Phase Redundancy Power Supervisor

MAX5973, Phase Redundancy Power Supervisor

The MAX5973 protects individual slave phases of a phase redundant DC-DC converter.

The power protection functions comprise an electronic circuit-breaker controller driving an external n-channel MOSFET at the step-down power input, and an internal 3.3V switch for the slave phase-controller power.
