ADM 1166
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)
• 10 programmable driver outputs, PDO1 to PDO10 (PDOx)
• Sequencing engine (SE) implements state machine control of PDO outputs
• 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
• 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

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