BL6501A Single Phase Energy Meter IC
FEATURES
High accuracy, less than 0.3% 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
Two current monitors continuously monitor the phase and neutral currents in two-wire distribution systems. Uses the larger of two currents to bill, even during a Fault condition
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
Two logic outputs REVP and FAULT can be used to indicate a potential orientation or Fault condition
On-Chip power supply detector On-Chip anti-creep protection On-Chip voltage reference of 2.44V ± 8% (typical temperature coefficient of 30ppm/℃),with external overdrive capability Single 5V supply Low static power (typical value of 15mW). The technology of SLiM (Smart–Low–current– Management ) is used.
Interrelated patents are pending
DESCRIPTION
The BL6501A is a low cost, high accuracy, high stability, simple peripheral circuit electrical energy meter IC. The meter based on the BL6501A is intended for using in single-phase, two-wire distribution systems. It can exactly measure the real power in the positive orientation and negative orientation and calculate ...
