Abstract
Power supplies are enabled and disabled in sequence in dependence upon monitored output voltages of, and an input voltage for, the power supplies. Bits stored in registers for each power supply represent the predetermined sequences in which the power supplies are enabled and disabled, and fault dependencies for the power supplies. The sequences can include independent, linear, divergent, and convergent paths. The registers are loaded from a non-volatile memory on power-up of a power supply controller also powered from the input voltage.
