Super Sequencer with Margining Control and Non-Volatile Fault Recording
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
- Multivoltage system line cards
- DSP/FPGA supply sequencing
- In-circuit testing of margined supplies
