BL0930

FEATURES BL0930 Single Phase Energy Meter IC with Integrated Oscillator DESCRIPTION High accuracy, less than 0.1% error over a dynamic range of 500 : 1 Exactly measure the real power in the positive orientation and negative orientation, calculate the energy in the same orientation A PGA in the current channel allows using small value shunt and burden resistance The low frequency outputs F1 and F2 can directly drive electromechanical counters and two phase stepper motors and the high frequency output CF, supplies instantaneous real power, is intended for calibration and communications The logic outputs REVP can be used to indicate a potential orientation Low static power (typical value of 15mW). The technology of SLiM (Smart–Low–current– Management ) is used. On-Chip power supply detector On-Chip anti-creep protection On-Chip oscillator On-Chip voltage reference of 2.5V±8% (typical temperature coefficient of 30ppm/℃)，with external overdrive capability Single 5V supply Interrelated patents are pending The BL0930 is a low cost, high accuracy, high stability, simple peripheral circuit electrical energy meter IC. The meter based on the BL0930 is intended for using in single-phase, two-wire distribution systems. The BL0930 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. Moreover, BL0930 supplies the negative orien...
