摘　　要：介绍了SA9904B,ATT7026A及CS5463等三相高精度电能计量芯片的原理,比较了芯片的性能指标。SA9904B提供有功、无功电能,但不提供视在功率和相角等参数;ATT7026A提供各分相、合相参数,但不具有中断功能;CS5463不但提供各种计量参数,且具有中断,更有低于12 mW的超低功耗。The principle of poly phase muhifunctional energy metering IC in three kinds of SA9904B,ATI/026A and CS5463 are introduced.The performance of the three chip are compared.SA9904B supplies active and reactive power/energy measurement, but it does not supply power-factor or phasor information; ATT7026A supplies the split phase and three phase information,but it does not offer the function of interrupt,CS5463 supplies several indirect parameters,and supplies information of interupt,and with 12mW lowest power loss.

关 键 词：电能计量芯片 中断 SPI串行接口 有功 无功
