SmartDV’s PMBus Slave IP is a silicon-proven, fully featured power management bus solution purpose-built for power management IC and peripheral SoC designs requiring reliable, standards-compliant communication with a PMBus master controller. Fully compliant with PMBus v1.4.1 Part II and I2C v7.0, it delivers complete slave-side PMBus functionality with support for the full PMBus command set, Zone Write and Read operations, packet error checking, alert generation, and comprehensive fault management — making it an ideal solution for voltage regulators, PMICs, and other power management peripherals in server, data center, automotive, and embedded applications.
Designed to give power management IC teams a production-tested, spec-complete PMBus slave implementation, the IP supports clock stretching for flexible timing adaptation, timeout detection and generation for robust bus fault recovery, slave arbitration, and general call address handling. Its comprehensive fault management and alert generation capabilities make it well-suited for safety-critical server and automotive power management designs where reliable fault reporting and bus integrity are critical design requirements.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its parameterized architecture and clean host interface enable fast integration and confident design bring-up across a wide range of process nodes and power management peripheral applications.
