com 19-5243; Rev 0; 4/10 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 differential analog error signals for the phase controller are also buffered.
An overvoltage comparator and switched-node monitoring function allows the MAX5973 to disable a phase that has a shorted (or latched-on) high-side MOSFET.
A fault-status output and a FAULTIN input allow a master device to monitor and control each MAX5973 device.
The MAX5973 is offered in a 5mm x 5mm, 40-pin TQFN package and is fully specified from -40NC to +85NC.
