ADM1166 Super Sequencer with Margining Control and Non-Volatile Fault Recording

Applications

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.

Supply margining can be performed with a minimum of external components. The margining loop can be used for in-circuit testing of a board during production (for example, to verify board func-tionality at −5% of nominal supplies), or it can be used dynamically to accurately control the output voltage of a dc-to-dc converter.

Features and Benefits
  • 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
