GENERAL DESCRIPTION
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.

FEATURES
   Complete supervisory and sequencing solution for up to
      10 supplies
   10 supply fault detectors enable supervision of supplies to
      <0.5% accuracy at all voltages at 25°C
      <1.0% accuracy across all voltages and temperatures
   5 selectable input attenuators allow supervision of supplies to
      14.4 V on VH
      6 V on VP1 to VP4 (VPx)
   5 dual-function inputs, VX1 to VX5 (VXx)
      High impedance input to supply fault detector with
         thresholds between 0.573 V and 1.375 V
      General-purpose logic input
   10 programmable driver outputs, PDO1 to PDO10 (PDOx)
      Open-collector with external pull-up
      Push/pull output, driven to VDDCAP or VPx
      Open collector with weak pull-up to VDDCAP or VPx
      Internally charge-pumped high drive for use with external
         N-FET (PDO1 to PDO6 only)
   Sequencing engine (SE) implements state machine control of
      PDO outputs
         State changes conditional on input events
         Enables complex control of boards
         Power-up and power-down sequence control
         Fault event handling
         Interrupt generation on warnings
         Watchdog function can be integrated in SE
         Program software control of sequencing through SMBus
   12-bit ADC for readback of all supervised voltages
   2 auxiliary (single-ended) ADC inputs
   Reference input (REFIN) has 2 input options
      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
   User EEPROM: 256 bytes
   Industry-standard 2-wire bus interface (SMBus)
   Guaranteed PDO low with VH, VPx = 1.2 V
   Available in 40-lead, 6 mm × 6 mm LFCSP and
      48-lead, 7 mm × 7 mm TQFP packages

APPLICATIONS
   Central office systems
   Servers/routers
   Multivoltage system line cards
   DSP/FPGA supply sequencing
   In-circuit testing of margined supplies
