GENERAL DESCRIPTION
The ADM1064 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 which 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
      better than 1% accuracy
   5 selectable input attenuators allow supervision:
      Supplies up to 14.4 V on VH
      Supplies up to 6 V on VP1–4
   5 dual-function inputs, VX1–5:
      High impedance input to supply fault detector with
         thresholds between 0.573 V and 1.375 V
      General-purpose logic input
   10 programmable output drivers (PDO1–10):
      Open collector with external pull-up
      Push/pull output, driven to VDDCAP or VPn
      Open collector with weak pull-up to VDDCAP or VPn
      Internally charge-pumped high drive for use with external
         N-FET (PDO1–6 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 2.048V (±0.25%) REFOUT pin
      More accurate external reference for improved ADC
         performance
   Device powered by the highest of VP1–4, VH for improved
   redundancy
   User EEPROM: 256 bytes
   Industry-standard 2-wire bus interface (SMBus)
   Guaranteed PDO low with VH, VPn = 1.2 V
   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
