BL6533

BL6533 Single Phase, LCD, Energy Meter IC FEATURES 1 High accuracy, less than 0.1% error over a dynamic range of 500 : 1 2 Exactly measure the real power in the positive orientation and negative orientation, calculate the energy in the same orientation 3 18×4 bit RAM for display data storage 4 Single 5V supply The BL6533 is a low cost, high accuracy, high stability, simple peripheral circuit electrical energy meter IC. The meter based on the BL6533 is intended for using in single-phase, two-wire distribution systems. The BL6533 adopts the oversample technology and digital signal processing technology. It can exactly measure the real power in the positive orientation and negative orientation and calculate the energy in the same orientation. BL6533 thinks over the stability of reading error in the process of calibration.. An internal no-load threshold ensures that the BL6533 does not exhibit any creep when there is no load. ◆ BL6533 System http://www.belling.com.cn -1Total 10 Pages 9/9/2009 BLOCK DIAGRAM BL6533 Single Phase Energy Meter IC with LCD Driver LQPF64 http://www.belling.com.cn -2Total 10 Pages 9/9/2009 PIN DESCRIPTIONS BL6533 Single Phase Energy Meter IC with LCD Driver Pin 1 2,3,4,5 6,7 8 9 10,11 12 13,14,15,16 17 18 19,20 21 22 23 24 25 26 27 28 29 30 31 32 33,34 35 36 37 38 39 40 41 Symbol VDD NC V1P,V1N NC V2P NC GND NC GND VLCD V1,V2 Com0 Com1 Com2 Com3 Seg17 Seg16 Seg15 Seg14 Seg13 Seg12 Seg11 Seg10 NC Seg9 Seg8 Seg7 Seg6 Seg5 Seg4 Seg3 DESCR...
