Interrelated patents are pending GENERAL DESCRIPTION The BL0952A/BL6513/BL6511 is the chief IC of the three-phase electrical meter and a high accuracy energy measurement IC. With low power design, static power is only 25mW. Based on the features such as superior accuracy, high stability and simple peripheral circuit, the BL0952A/BL6513/BL6511 is compatible with 3-phase 3-wire and 3-phase 4-wire configurations. BL0952A/BL6513/BL6511 is based on digital signal processing. BL0952A/BL6513/BL6511 can measure positive active power and negative active power; can select the way to calculate the sum of the three-phase active powers, between the arithmetic sum and the absolute value sum. The high frequency output CF can be used in calibration and data processing. The low frequency outputs F1 and F2 can be used to drive a pulse-motor or an electromechanical counter. In this way, the power can be measured and the energy can be recorded. The internal phase matching circuitry ensures that the current and voltage channels are phase matched.An internal no-load threshold ensures that the BL0952A/BL6513/BL6511 does not exhibit any creep when there is no load. The BL0952A/BL6513/BL6511 consider emphatically the need of stability during calibration, the measure data of mass products show that the output pulse ripple of CF is less than 0.1%.

The output frequency is proportional to the average active power. 2 DGND This provides the ground reference for the digital circuitry . 3 4 5,6; 7,8; 9,10 11 12 VDD REVP IAP,IAN; IBP,IBN; ICP,ICN AGND REF Power supply. This pin provides the supply voltage for the digital circuitry. The supply voltage should be maintained at 5V ± 5% for specified operation. This logic output will go logic high when negative power is detected on any of the three phase inputs, i.e., when the phase angle between the voltage and the current signals is greater than 90°. Analog inputs for current channel. These inputs are fully differential voltage inputs with maximum differential input signal levels of ±500mV This pin provides the ground reference for the analog circuitry. This pin provides access to the on-chip voltage reference. The on-chip reference has a nominal value of 2.42V ± 8% and a typical temperature coefficient of 30ppm/°C. An external reference source may also be connected at this pin. 13,14, 15,16 17 VN,VCP VBP,VAP ADDSEL Analog inputs for the voltage channel. This channel is intended for use with the voltage VBP, VAP transducer and is referenced as the voltage channel in this document. These inputs are single-ended voltage inputs with maximum signal level of ±500mV with respect to VN for specified operation. The logic input is used to select the way the three active energies from the three phases are summed. This offers the designer the capability to do the arithmetic sum of the three energies (ADDSEL logic High) or the sum of the absolute value (ADDSEL logic low). 18 19 20 21,22 23,24 SCF CLKIN CLKOUT S0,S1 F1,F2 Select Calibration Frequency. This logic input is used to select the frequency on the calibration output CF. Master clock for ADCs and digital signal processing. An external clock can be provided at this logic input.3.58MHz A crystal can be connected across this pin and CLKIN as described above to provide a clock source. These logic inputs are used to select one of four possible frequencies for the digital-to-frequency conversion. This offers the designer greater flexibility when designing the energy meter. Low Frequency Logic Outputs. F1 and F2 supply average real power information. The logic outputs can be used to directly drive electromechanical counters and two-phase stepper motors. http://www.belling.com.cn -2Total 2 Pages 4/21/2009 BL0952A/BL6513 Three-phase Activ.
