DESCRIPTION
The ADM1066 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 ADM1066 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- de 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 exarmple, 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
Complete supervisory and sequencing solution for up to10 supplies
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 atenuators alw supervision of supplies to 14.4V on VH6V on VP1 toVP4 (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, PD01 to PD010 (PDOx)
Open-collector with external pull-up
Push/pull output, driven to VDDCAP orVPx
Open collector with weak pull-up to VDDCAP or VPx
