Product Description

GENERAL DESCRIPTION
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)
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, driven to VDDCAP or VPx
Open collector with weak pull-up to VDDCAP or VPx
Internally charge-pumped high drive for use with external N-FET (PDO1 to PDO6 only)
Sequencing engine (SE) implements state machine control of
PDO outputs
State changes conditional on input events
Enables complex control of boards
Power-up and power-down sequence control
Fault event handling
Interrupt generation on warnings
Watchdog function can be integrated in SE
Program software control of sequencing through SMBus
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
Driven directly from 2.048 V (±0.25%) REFOUT pin
More accurate external reference for improved ADC performance
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
Available in 40-lead, 6 mm × 6 mm LFCSP and 48-lead, 7 mm × 7 mm TQFP packages
