Maxim Integrated Products Inc. has introduced a pair of single-phase energy-measurement processors that according to the company offers simple utility-grade sensing and diagnostics for existing designs without the traditional cost of a utility meter SoC. The processors are energy-measurement sub-systems in a single chip and both devices contain unique firmware to meet end application requirements, added the firm.

The 78M6610+PSU is engineered for real-time monitoring of data centres, 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, Maxim indicated.

The 78M6610 processors claim to 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 existing design without significant cost or redesign. Additionally, the processors' flexible measurement and host interfaces allow for easy integration into any system.

The 78M6610+PSU is available in a 24-pin QFN and 16-pin TSSOP package, while the 78M6610+LMU is available in a 24-pin QFN package. Both devices can be had for $1.99 for 1,000 pieces and up.
