Maxim is now sampling 78M6610+PSU/78M6610+LMU single-phase energy-measurement ICs packs energy-measurement subsystem in a single chip. Maxim says they provide simple utility-grade sensing and diagnostics for existing designs without the traditional cost of a utility meter system-on-chip. Both devices contain unique firmware to meet end application requirements. The 78M6610+PSU is designed for real-time monitoring of data centers, servers, and telecom and data equipment, while the 78M6610+LMU is a more general-purpose solution for applications such as white-good appliances, smart plugs, EV chargers, and solar inverters.
Key advantages as per Maxim:
High performance: utility-grade sensing over the entire dynamic range of load current and power-down modes
Reduced bill of materials (BOM) costs: internal RC oscillator and low baud rate serial interface eliminate the need for expensive and fragile crystals
Simplicity: firmware is optimized for end applications so design-in is greatly simplified
“A more efficient smart grid needs energy measurement at a variety of endpoints beyond the traditional electric meter,” said Kris Ardis, Business Director for Smart Grid Products at Maxim Integrated. “The 78M6610+PSU/78M6610+LMU enable these points of measurement with utility-grade accuracy, application-specific firmware, and at a low system cost.”
“The smart grid benefits from embedded technologies like these processors,” said Christine Hertzog, Managing Director at Smart Grid Library. “They reduce BOM costs and encourage more widespread deployment of energy-measurement intelligence across the electricity value chain.”
