ADM1064 Super Sequencer® with Voltage Readback 12-bit ADC

The ADM1064 Super Sequencer® is a configurable supervisory/ sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems. In addition to these functions, the ADM1064 integrates a 12-bit ADC that can be used to accurately read back up to 12 separate voltages. Central office systems Servers/routers Multivoltage system line cards DSP/FPGA supply sequencing In-circuit testing of margined supplies

The device also provides up to 10 programmable inputs for moni-toring undervoltage faults, overvoltage faults, or out-of-window faults on up to 10 supplies. In addition, 10 programmable outputs can be used as logic enables. Six of these programmable outputs can provide up to a 12 V output for driving the gate of an N-FET that can be placed in the path of a supply.
