BL6501

Features:

* 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
* 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

* 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 2.42V ± 8% (typical temperature coefficient of 30ppm/),with external overdrive capability
* Single 5V supply
* Low static power (typical value of 15mW).The technology of SLiM (SmartLowcurrentManagement ) is used.
* Credible work, working time is more than twenty years

Description

The BL6501 is a low cost, high accuracy, high stability, simple peripheral circuit electrical energy meter IC. The meter based on the BL6501 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 the energy in the same orientation.

The BL6501 incorporates a novel fault detection scheme that both warns of fault conditions and allows the BL6501 to continue accurate billing during a fault event. The BL6501 does this by continuously monitoring both the phase and neutral (return) currents. Fault condition is indicated by PIN19 (FAULT), when these currents differ by more than 12%. Billing is continued using the larger of the two currents when the difference is greater than 14%.

The BL6501 supplies average real power information on the low frequency outputs F1 (Pin23) and F2 (Pin24). These logic outputs may be used to directly drive an electromechanical counter and two-phase stepper motors. The CF (Pin22) logic output gives instantaneous real power information. This output is intended to be used for calibration purposes or interface to an MCU.

BL6501 thinks over the stability of reading error in the process of calibration.. An internal no-load threshold ensures that the BL6501 does not exhibit any creep when there is no load.
