BANGALORE, India Analog Devices unveiled two families of single-chip energy meter ICs here with intelligent battery management for energy meters.
The ADE7169 was designed for Indian utility requirements. The Indian energy market is estimated to include 10 million single-phase energy meters.
"The ADE7169 is scheduled for release early next year. We anticipate meter manufactures to take up to six
months to complete their design, quality and
reliability evaluations and testing. Meters with the
ADE7169 will be available to utilities in the second
half of 2007," said Mark Strzegowski, Analog Devices' senior product manager.
The ADE7169 chip performs functions which previously required as many as six discrete ICs. It includes
intelligent battery modes to sense temperature changes, operate an LCD readout and perform other functions such as supplying voltage during power outages. It uses at least 40 percent less power than other solutions, Strzegowski claimed.
The ADE7169 is available in 64-lead low-profile quad flat packages and is priced under $3.00 per unit in 1,000-piece quantities.
