Maxim Integrated Products Inc. unveils the 78M6610+PSU / 78M6610+LMU single-phase energy-measurement processors in a single chip.

The devices are said to provide utility-grade sensing over the entire dynamic range of load current and power-down modes. They feature diagnostics for existing designs without the traditional cost of a utility meter system-on-chip. They have firmware to meet end application requirements. The 78M6610+PSU is designed for real-time monitoring of datacentres, servers, and telecom and data equipment, while the 78M6610+LMU is a general-purpose solution for white-good appliances, smart plugs, EV chargers and solar inverters.

The 78M6610 processors enable energy-measurement functionality while reducing both manufacturing costs and time to market. Energy-measurement solutions traditionally required the use of an additional microcontroller, which adds significant design cost and months of development time. The 78M6610 allow users to conveniently add a complete energy meter to an already existing design without significant cost or redesign. Additionally, the processors' flexible measurement and host interfaces allow for easy integration into any system.

The devices offer less BOM by integrating an internal RC oscillator and low baud rate serial interface, cutting need for expensive and fragile crystals. Also,

The 78M6610+PSU is available in both 24-pin QFN and 16-pin TSSOP packages, while the 78M6610+LMU is available only in the 24-pin QFN package. Pricing for the 78M6610+PSU/78M6610+LMU starts at Rs.108.74 ($1.99) (1000-up, FOB USA).
