Dolphin Integration empowers the Smart Metering market with a dense and low BoM panoply for class 0.1 reaching 1:10,000 systems

Power metering is the basic function to enable smart grids, thanks to a precise and low-cost control of power consumption for ecological and economic matters.

Grenoble, France – July 6, 2012 --Dolphin Integration, silicon IP leader in high-resolution converters for integrated circuits, offers an Analog Front-End for Power-metering reaching 20 bits of sensitivity. This AFE at 180 nm enables to satisfy the needs of a system targeting the highest performances: up to a class of 0.1 over a range of 1/10,000. The user thus benefits from a high precision measurement for either accurate billing, or wise device power management.

This offering benefits from a new design:

• highest density for the logic part and thus, minimization of power waste
• lowest Bill-of-Material thanks to the removal of external capacitors
• best sensitivity of the measurement thanks to an Automatic Gain Control enabling to adapt the gain to the signal amplitude, and allowing to reach a larger range with current transformers
• larger range for each gain, enabling to reach class and range with cheaper sensors such as shunt resistors.

The first configuration benefiting from such a design, sensAFE-20x32-PM-mono.04-LB, delivers a complete solution:

• 1 current path and 1 voltage path for the basic measurement of power
• 1 tampering path for detecting any electricity theft on either consumer or supplier networks
• 1 reference voltage presenting a low drift, compatible with class 0.1 and facilitating the calibration
• 1 linear regulator for the analog power supply insuring the lowest noise and thus, insured performances after integration
