ROHM Enhances Automotive Solutions with Innovative Hall ICs

Category articles

With automotive industry’s relentless march toward greater electrification, functionality, comfort, and safety, demand for sophisticated electronic control units (ECUs) and sensors has significantly increased. Hall effect sensors – commonly referred to as Hall ICs – have become one of the most utilized sensors due to their remarkable ability to detect magnetic fields efficiently and reliably; making them perfect for applications requiring precise magnetic detection with greater efficiency and reliability.

ROHM, an industry-leader in semiconductor and electronic component production, recently unveiled an innovative Hall IC series: the BD5310xG-CZ/BD5410xG-CZ series. These Hall ICs were specifically developed to meet the magnetic field detection needs of automotive applications – an increasingly computerized vehicle system’s need.

Hall ICs have become an indispensable component of automotive electronics due to their versatile abilities. Hall ICs excel in detecting motor position and rotation with non-contact magnetic field sensing technology, unlike traditional mechanical switches which wear down over time due to wear and tear. Furthermore, these compact devices come equipped with protection circuits which further strengthen their robustness and reliability.

ROHM’s venture into automotive Hall ICs has drawn on their years of expertise in this sector. Drawing upon mobile and consumer sector Hall IC development experience combined with innovative high withstand voltage processes has produced remarkable achievements; including their BD5310xG-CZ/BD5410xG-CZ series featuring an outstanding 42V withstand voltage rating for direct connection to primary 12V battery supplies; essential features in an industry where battery voltage fluctuations occur rapidly due to fluctuating operating conditions.

A series of Hall ICs with an operating supply voltage range from 2.7V to 38V makes these adaptable to numerous automotive applications, and their unique internal design contributes to an approximately 20% decrease in power consumption compared to general products, leading to industry-leading current consumption at 1.9mA – both increasing performance while aligning with the automotive industry’s heightened emphasis on energy-saving solutions.

For greater assurance in quality, both the BD5310xG-CZ and BD5410xG-CZ series conform to the AEC-Q100 (Grade 1) automotive reliability standard. This certification ensures that these Hall ICs can withstand the challenges presented by automotive environments while improving overall system reliability.

Distinguishing this series even further is its versatility for designers. The BD5310xG-CZ series employs unipolar detection, making it suitable for applications involving position detection like door open/close mechanisms and locks; on the other hand, the BD5410xG-CZ series employs latch-type detection which makes it suitable for rotation detection in motors that power power windows, sliding doors, etc.

ROHM remains committed to innovation and expansion. Their expansion of sensor IC offerings showcases their dedication to delivering solutions that improve reliability and functionality within automotive applications. As electronics are becoming an integral component of efficiency and performance, ROHM Hall ICs stand to have an important impact.

What Is Hall IC

A Hall IC (or Hall effect sensor or integrated circuit) is a semiconductor device that utilizes the Hall effect to detect magnetic fields. This fundamental principle in physics generates a voltage difference across conductors or semiconductor materials when exposed to perpendicular magnetic fields while an electric current flows through them; this phenomenon is known as the Hall voltage difference.

Hall ICs are increasingly used in various applications due to their non-contact magnetic field sensing capabilities. Their non-invasive nature enables them to detect changes in magnetic fields, making them perfect for applications such as position sensing, speed measurement and rotation detection in various devices and systems.

Hall ICs have become indispensable components in automotive systems and other industries where precise magnetic field detection is required, providing benefits like durability, reliability and compactness that make them essential components of modern systems and industries.
