ADM1069ASTZ Dettagli del prodotto

GENERAL DESCRIPTION
The ADM1069 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 ADM1069 integrates a 12-bit analog-todigital converter (ADC) and four 8-bit voltage output digital-toanalog converters (DACs). These circuits can implement a closedloop margining system that enables supply adjustment by altering either the feedback node or reference of a dc-to-dc converter using the DAC outputs.

FEATURES
   Complete supervisory and sequencing solution for up to
      8 supplies
   8 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
   4 selectable input attenuators allow supervision of supplies to
      14.4 V on VH
      6 V on VP1 to VP3 (VPx)
   4 dual-function inputs, VX1 to VX4 (VXx)
      High impedance input to supply fault detector with
         thresholds between 0.573 V and 1.375 V
      General-purpose logic input
   8 programmable driver outputs, PDO1 to PDO8 (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
   Complete voltage margining solution for 4 voltage rails
   4 voltage output 8-bit DACs (0.300 V to 1.551 V) allow voltage
      adjustment via dc-to-dc converter trim/feedback node
   12-bit ADC for readback of all supervised voltages
   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 32-lead, 7 mm × 7 mm LQFP and 40-lead,
      6 mm × 6 mm LFCSP packages

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