Zero Crossing Latch - a New Detection Methodology which turns a new page in brushless DC motor development

3 Advantages the Zero Crossing Latch Hall Effect IC Brings to Motor Design

3 Advantages the S-576Z series 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 Zero Crossing Latch 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 Zero Crossing Latch 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.


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

To make a compact and low-profile motor housing, it is essential to reduce the size of the magnets and the distance between the sensor PCB and the magnets.

Zero Crossing Latch 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.


 Specifications defined for designer

・Static Electricity Countermeasures

To cope with the harsh environment during motor installation, it has a dielectric withstanding voltage of HBM: 8,000V.

・Built-in Pull-up Resistor

S-576Z B Series integrate a 1.2kΩ pull-up resistor, which is ideal for reducing the delay in the rise and fall times of signal output.

・Wide Operating Voltage Range

The wide operating voltage range of 2.7V - 26.0V ensures stable sensor signal output at motor start and stop.

Application Examples

Robots (brushless DC motors for vertical movement and operation of joints)

Electric power tools, cordless vacuum cleaners, etc.

High energy efficiency, reliability, low-noise performance and other characteristics make it ideal in consumer products that require granular control.
