Teridian Semiconductor is sampling their new 71M6541x and 71M6xx1 residential smart metering integrated circuits (ICs). The 71M6541x and 71M6xx1 feature digitally isolated current sensors based on their MicroDAA isolation technology. By incorporating isolation technology into the metering solutions, Teridian have overcome traditional barriers associated with the use of resistive shunts in multi-phase applications.
The 71M6541x, as a stand-alone meter system-on-chip (SoC) for single element meters, offers reduced power consumption and enhanced accuracy. The 71M6xx1 isolated sensor IC eliminates current transformer and associated copper wiring in 2-element residential meters, with up to class 0.2 accuracy (ANSI 200A). The result is up to 25% reduction in bill of materials (BOM) costs for residential applications.
The 71M6541x is offered in 64-pin LQFP packages with 32KB or 64KB Flash options and prices starting at $2.00 at 10,000 quantities. The 71M6xx1 isolated sensors are offered in 8-pin SOIC packages with prices starting at $1.50 for 10,000 quantities, which varies depending on current and accuracy range.
