Automotive Hall Effect ICs

1. Detection Types of ABLIC’s Hall Effect ICs

ABLIC offers both Hall effect latch and switch ICs in the world’s thinnest class packages to meet the needs of a wide variety of devices used in automobiles for motion detection.
Users can select the bipolar latch or the newly developed ZCL detection method for Hall effect latch ICs for motor control and rotation detection, and the unipolar or omnipolar detection method for Hall effect switch ICs for detecting opening, closing and sliding motion.
Please refer to our product lineupour product lineup for products using the different detection methods.

2. Innovating the Design and Manufacture of Automotive Brushless DC Motors Using ZCLTM Hall Effect ICs

A ZCL (=Zero Crossing Latch) Hall effect IC is a latch type Hall effect IC that uses a world first detection methodology to change the output signal at the zero-crossing point where polarity changes. Optimized for brushless DC (BLDC) motors, this Hall effect IC is not thrown off by changes in magnetic flux density and therefore provides stable detection.

Complex control programs are not needed to create a motor that runs smoothly.

A ZCL Hall effect IC is not easily affected by variations in magnets or changes in magnetic flux density and provides the expected rotation detection. Smooth motor rotation is obtained without complex program control.

Features of ZCL Hall effect IC: Helps create a motor that runs smoothly

Striving for a high efficiency motor that reduces the need for calibration

Rotation detection unaffected by temperature change or design tolerances is a ZCL Hall effect IC characteristic. Use a ZCL Hall effect IC to create a motor that will be able to constantly operate at full torque without calibration. Nor will it be affected by drops in efficiency due to temperature changes or design tolerances.

Features of ZCL Hall effect IC: Strives for a high efficiency motor

Providing an Innovative Sensor Layout

Regardless of the magnitude of magnetic flux density, as long as the changes in the magnetic flux received by a ZCL Hall effect IC are in the correct phase, these sensor ICs can be installed almost anywhere.
*However, the magnetic flux density received by a ZCL Hall effect IC must exceed the release point.
