Analog Devices MAX20810 PMBus Command Set User Guide
Detailed guide to PMBus commands for the MAX20810 step-down regulator, covering communication protocols, device configuration, status monitoring, and telemetry readings.
Overview
This user guide provides a comprehensive list and description of the Power Management Bus (PMBus) commands implemented in the MAX20810 integrated step-down switching regulator. Based on PMBus Revision 1.3 specifications, the document details standard commands, manufacturer-specific additions, and deviations from standard functionality. It includes technical specifications for communication protocols such as Read/Write Byte, Word, and Block transactions. Key sections cover output voltage control, switching frequency configuration through MFR_SCENARIO registers, status reporting for faults (VOUT, IOUT, Temperature, CML), and real-time telemetry for monitoring input voltage and device temperature.
Use Cases
- Configuring output voltage and switching frequency in power system designs.
- Implementing real-time system monitoring for voltage, current, and thermal telemetry.
- Developing firmware for PMBus-compliant power management controllers.
- Troubleshooting power supply faults using standard and manufacturer-specific status registers.
