ADM1166 Détails du produit

GENERAL DESCRIPTION

The ADM1166 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 ADM1166 integrates a 12-bit ADC and six 8-bit voltage output DACs. These circuits can be used to implement a closed-loop 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 10 supplies

  16 event deep black box nonvolatile fault recording

  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

  Complete voltage-margining solution for 6 voltage rails

  6 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

  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

  For more information about the ADM1166 register map, refer to the AN-698 Application Note



APPLICATIONS

  Central office systems

  Servers/routers

  Multivoltage system line cards

  DSP/FPGA supply sequencing

  In-circuit testing of margined supplies
