Phase Redundancy Power Supervisor MAX5973
General Description
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.
To protect the output bus, an “ideal diode” controller drives an external n-channel MOSFET at the slave phase output.
Serial data to and from the slave phase is buffered by the MAX5973 to prevent a failure of one phase from interrupting communication to the remaining phases.
Similarly, the differe...
