DACs use a proprietary soft-connect algorithm to minimize supply disturbances. Supervisory functions include over and under voltage and temperature threshold limits for two power supply output channels and one input channel. Programmable fault responses can disable the power supplies, config- ure retry, and trigger black box EEPROM storage of fault status and associated telemetry. An internal 16-bit ADC monitors two output voltages, two output currents, two external temperatures, input voltage and current, and die temperature. Input power, energy, and output power are alsocalculated.Aprogrammablewatchdogtimermonitors microprocessor activity and resets if necessary. A single wirebussynchronizespowersuppliesacrossmultipleADI Power System Management (PSM) devices. Configura- tion EEPROM with ECC supports autonomous operation without additional software.
