ADM1069:  Compact Multi- Voltage Sequencer and Supervisor with Margining Control

Product 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 ADC and four 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.

Applications

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

    • 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
    • See data sheet for additional features
