The ZCL hall effect IC is
a new generation of Hall effect ICs
that change the output signal at the
point polarity changes (zero crossing point) and employs

the world’s first*1 detection method optimized for
brushless DC motor control.

3 Advantages the ZCL Hall effect IC Brings to Motor Design


Rotation angle detection is not easily impacted by changes in magnetic flux

Rotation angle detection is not easily impacted by changes in magnetic flux

The Hall effect IC for BLDC motor control applies the magnetic flux density from rotating magnets.

The ZCL Hall Effect IC changes the signal output at the point polarity changes(zero crossing point), without depending on the magnitude of the magnetic flux density.

Zero cross point is constant because it is not affected by changes in the distance between the magnets and the sensor or changes in temperature.

The ZCL Hall effect IC simplifies complex software calibrations and tolerance calculations. These advantages further simplify the design of DC motors with constant high efficiency and low noise characteristics.

Compact and Low profile motor housing

[World’s Top Class] Compact & Low Profile Motor Housing

ZCL technology ensures detection even of magnetic flux generated by tiny magnets.
To apply this technology to its fullest possible extent, the S-576Z B Series IC is made available in a surface mount package that enables highly flexible placement.

This new package is the TSOT-23-3S (2.9 x 2.8 x t0.8mm), the world’s lowest profile package, which shrinks the distance between the magnet and the PCB to the footprint of the world standard SOT-23-3 (2.9 x 2.8 x t1.3mm) package.
