<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 up to 14.4 V on VH
Supplies up to 6 V on VP1 to VP4 (VPn) - 10 programmable output drivers (PDO1 to PDO10):
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

Product Details
The ADM1062 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 ADM1062 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 the reference of a dc-to-dc converter using the DAC outputs.
For more information about the ADM1062 register map, refer to the AN-698 Application Note.
APPLICATIONS
- Central office systems
- Servers/routers
- Multivoltage system line cards
- DSP/FPGA supply sequencing
- In-circuit testing of margined supplies
