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. APPLICATIONS * Central office systems * Servers/routers * Multivoltage system line cards * DSP/FPGA supply sequencing * In-circuit testing of margined supplies * 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) https://elecena.pl/product/1632975/super-sequencer-with-margining-control-and-non-volatile-fault-recording 2011-04-02 https://elecena.pl/product/1632975/super-sequencer-with-margining-control-and-non-volatile-fault-recording 2018-03-29 https://elecena.pl/product/1632975/super-sequencer-with-margining-control-and-non-volatile-fault-recording 2025-01-19
