●The ADM1063 series Multisupply Supervisor/Sequencer with ADC and temperature monitoring. The configurable supervisory/sequencing device offers a single-chip solution for supply monitoring and sequencing in multiple supply systems. In addition to these functions, the ADM1063 integrates a 12-bit ADC that can be used to accurately read back up to 12 separate voltages. The device also provides up to 10 programmable inputs for monitoring under, over 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 12V output for driving the gate of an N-FET that can be placed in the path of a supply.
● Complete supervisory and sequencing solution for up to 10 supplies
● 10 Supply fault detectors enable supervision of supplies <0.5% accuracy at all voltages at 25°C
● 5 Selectable input attenuators allow supervision of supplies to 6V on VP1 to VP4 (VPx)
● 5 Dual-function inputs, VX1 to VX5 (VXx) - general-purpose logic input
● 10 Programmable driver outputs, PDO1 to PDO10 (PDOx) - Open-collector with external pull-up
● Sequencing engine (SE) implements state machine control of PDO outputs
● Complete voltage margining solution for 6 voltage rails
● 12-bit ADC for readback of all supervised voltages
● 1 Internal and 2 external temperature sensors
● Driven directly from 2.048 V (±0.25%) REFOUT pin
● More accurate external reference for improved ADC performance
● Device powered by the highest of VPx, VH for improved redundancy
