BL6501A Single Phase Energy Meter IC ‹ Features D High accuracy, less than 0.3% error over a ‹ DESCRIPTION The BL6501A is a low cost, high accuracy, high dynamic range of 500 : 1 D Exactly measure the real power in the positive stability, simple peripheral circuit electrical energy meter IC. The meter based on the BL6501A is orientation and negative orientation, calculate the intended for using in single-phase, two-wire energy in the same orientation D Two current monitors continuously monitor the distribution systems. It can exactly measure the real power in the positive orientation and negative phase and neutral currents in two-wire distribution orientation and calculate the energy in the same systems. Uses the larger of two currents to bill, even orientation. during a Fault condition D A PGA in the current channel allows using small The BL6501A incorporates a novel fault detection scheme that both warns of fault conditions value shunt and burden resistance D The low frequency outputs F1 and F2 can and allows the BL6501A to continue accurate billing during a fault event. The BL6501A does this by directly drive electromechanical counters and two continuously monitoring both the phase and neutral phase stepper motors and the high frequency output (return) currents. Fault condition is indicated by CF, supplies instantaneous real power, is intended for PIN19 (FAULT), when these currents differ by more calibration and munications D Two logic outputs REVP and FAULT can be used than 12%. Billing is continued using the larger of the two currents when the difference is greater than 14%. to indicate a potential orientation or Fault condition D On-Chip power supply detector D On-Chip anti-creep protection D On-Chip voltage reference of 2.44V ± 8% (typical temperature coefficient of 30ppm/℃)，with The BL6501A supplies average real power information on the low frequency outputs F1 (Pin23) and F2 (Pin24). These logic outputs may be used to directly drive...
