BL6533
Single Phase, LCD, Energy Meter IC
FEATURES
1 High accuracy, less than 0.1% error over a
dynamic range of 500 : 1
2 Exactly measure the real power in the positive
orientation and negative orientation, calculate
the energy in the same orientation
3 18×4 bit RAM for display data storage
4 Single 5V supply
The BL6533 is a low cost, high accuracy, high
stability, simple peripheral circuit electrical energy
meter IC. The meter based on the BL6533 is intended
for using in single-phase, two-wire distribution
systems.
The BL6533 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.
BL6533 thinks over the stability of reading
error in the process of calibration.. An internal no-load
threshold ensures that the BL6533 does not exhibit
any creep when there is no load.

TERMINOLOGY
1) Measurement Error
The error associated with the energy measurement made by the BL6533 is defined by the following
formula:
2) Nonlinear Error
The Nonlinear Error is defined by the following formula:
eNL%＝[(Error at X-Error at Ib) / (1+Error at Ib )]*100%
