TDK unveils new Hall-effect 2D position sensor family for automotive applications

Highlights:

• HAL/HAR 35xy is a family of 2D Hall-Effect 2D Sensors of Hall Hall Hall Hall Hall Hall of Hall 2D Hall with improved features for critical automotive applications of critical safety
• The new sensors include a single -abode version (HAL 3550) and a double death version (HAR 3550) with analog output interfaces (linear, ratiometric) and digital (PWM, Ent and Switch)
• Based on the emblematic family of HAL/HAR 39xy microns, which offers a more profitable option without sacrificing performance or functional safety performance
• The main objective applications are the steering wheel angles, brake pedal and accelerator positions, valve positions and chassis position detection

TDK Corporation presents the family of cash position sensors HAL/HAR 35XY 2D street field for the family of the Hall 2D effect position for automotive and industrial applications. On the basis of the success of the HAL/HAR 39xy series, the new sensors offer improved characteristics and capabilities to meet the growing demand for the detection of 2D robust of street field in linear and angular applications. Although the HAL/HAR 39XY family focuses on high flexibility, various characteristics and interfaces, and higher performance, Hal/HAR 35xy is designed for conventional applications that require a central characteristic with reduced flexibility, while maintaining high standards in functional safety and performance. With the versatile programming, high precision and compliance with ISO 26262, HAL/HAR 35xy is a potential solution for critical safety automotive applications, including accelerator pedals, the brake pedal position or brake stroke sensors, the detection of the direction angle, the valve position, such as the accelerator, the change position of change of change, the potential position, the potential Position of the transmission and height of the height of the Chasta. June 2025. Samples are already available.

The first sensors of the new family include Hal 3550, a single -dwelling version and HAR 3550, a double death version that provides complete redundancy with two independent troches housed in a single package. The new family of sensors is designed to meet the strict functional safety requirements compatible with ISO 26262. Hal 3550 and HAR 3550 are defined as an out of context safety (SEOOC) and are ready for asylum C, which makes them adequate for integration into automotive security systems to Asil D.

HAL 3550 and HAR 3550 are high -resolution position sensors designed for precise position measurements, with a linear ratiometric analog output with passive wire break detection, as well as PWM outputs or configurable sent outputs. The envoy mode admits messages with or without pause pulse, adhering to SAE J2716 Rev. 4 standards, with customizable parameters, such as tick time and the table format. The PWM output offers flexibility with frequencies ranging from 0.1 KHz to 2 kHz. In addition, Hal/HAR 3550 offers a switch output (open drain), derived from calculated position information or other sources along the signal route, such as the temperature or amplitude of the magnetic field. Users can define the switching points of ignition/off, the logic of change and polarity to meet their specific application needs.

Able to measure a complete angular range of 360 ° and linear movements of a magnet, the sensors are particularly suitable for chassis position sensors applications, with a module function that allows the 360 ​​° measurement range to be divided into sub-segments of 90 °, 120 ° or 180 °.

Using hall technology, HAL/HAR 3550 measures the vertical and horizontal components of magnetic field and effectively suppress external magnetic street fields with a variety of lounge plates. A low -cost single -pole ferrite magnet is sufficient for rotation angle measurements, ideally placed in an axis end configuration. The sensors also admit robust measurements outside the street axis.

The signal processing capabilities in chip allow the calculation of an angle per given of the magnetic field components. This information becomes an analog or digital output signal. Key characteristics such as gain, displacement and reference position can be adapted to magnetic circuits through programmable non -volatile memory.

Designed for automotive and industrial applications, the sensors operate within an ambient temperature range of –40 ° C to 150 ° C. are available in a SMD SMD SMD “for the single -death version and an SMD TSSOP16 package for the double death version.
