MAX5973 Datasheet Phase Redundancy Power Supervisor

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: .. 19-5243; Rev 0; 4/10 Phase Redundancy Power Supervisor MAX5973 General.

General Description

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

The power protection functions prise 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.

To protect the output bus, an “ideal diode” controller drives an external n-channel MOSFET at the slave phase output.
