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

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.

技术特性
  • 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
