ABLIC: Launch of the S-57TZ Series Today – Commercializing the ZCL™(*1) Hall Effect ICs for Automotive Use and Transforming the Brushless DC Motor Market –

ABLIC Inc. (President: Nobumasa Ishiai, head office: Chiba City, Chiba Prefecture; hereinafter “ABLIC”) today launched the S-57TZ Series of ZCL™ Hall effect ICs (magnetic sensors) for automotive use that are designed to transform the development and manufacture of brushless DC motors.
Announced in October 2018 as the World’s first (*2) ZCL™ Hall effect IC (magnetic sensor) with an innovative detection methodology, this product is now launched as a product for automotive use.

The S-57TZ Series is not a unipolar or bipolar Hall effect latch IC but a ZCL™ Hall effect IC, a consumer product with an entirely new detection methodology capable of changing the output signal at the point (zero crossing point) where the polarity changes.

The S-57TZ Series significantly improves flexibility at the design stage since it eliminates sensor positional accuracy and component variations and other negative impact on motor performance. It is a product that enables a reduction in the calibration work load in the manufacturing process and go a long way toward resolving the issues of motor developers and designers.

Compared to a bipolar Hall effect latch IC installed in a brushless motor (where sensor position is not optimal), a 15% or greater reduction in power consumption can be expected (*3), making it environmentally-friendly and also improving the performance of the product using the brushless motor.
It is also PPAP (Production Part Approval Process) capable and is designed to qualify for the AEC(*)-Q100 Grade 0 (* Automotive Electronics Council) standard for automotive ICs.

(*1) ZCL is an abbreviation of “Zero Crossing Latch.”
(*2) Based on our research as of September 2018.
(*3) Based on our research as of November 2019.

Major Features

1.A world first! The ZCL™ Hall effect IC employs an innovative detection method that differs from both unipolar and bipolar detection.
2. Properties required for internal automotive motor use
  1. A wide operating voltage range that promises stable sensor signal output at motor start and stop.
  2. Static electricity countermeasures to withstand harsh vehicle and motor assembly environments.
  3. A built-in reverse voltage protection circuit protects the Hall effect IC from damage that could occur if the voltage is accidentally reversed during battery connection or vehicle repair.
  4. A built-in pull-up resistor (an optional product) ideal for reducing differences in the rise and fall delay times of sensor signal output.
3. Automotive quality

The series has passed the three-temperature test (low, normal and high temperature) and will comply with the AEC-Q100 Grade 0 reliability and quality test defined by the AEC (Automotive Electronics Council). It is also in compliance with PPAP (Production Part Approval Process). These factors ensure it is well suited for the harsh environment that automotive applications present.

Application Examples

Automotive devices that demand high energy efficiency, reliability and low-noise performance such as power sliding doors and power back doors that operate when the ignition is off and fan motors and power seats that operate when the engine is off.
