Rohm Hall ICs Dominate with Superior High-Voltage Endurance

Rohm has introduced Hall ICs designed for automotive applications that need magnetic detection. With the growing computerization of vehicle systems to enhance electrification, functionality, comfort, and safety, more ECUs and sensors are required to manage control. Hall ICs are becoming increasingly popular among these sensors because they can detect position and motor rotation without contact, minimizing the wear and tear typically seen in mechanical switches. These ICs are also compact and can include protection circuits.

Rohm’s automotive Hall ICs leverage years of expertise from the mobile and consumer sectors, combined with innovative high-voltage processes, to boost reliability. The BD5310xG-CZ and BD5410xG-CZ series offer a 42V withstand voltage, allowing them to connect directly to a 12V car battery, thus enhancing reliability even when battery power fluctuates due to different operating conditions.

Moreover, these ICs support a wide operating supply voltage range of 2.7 to 38V, making them versatile for various applications. They also consume around 20% less power than standard products, with a current consumption of just 1.9mA. Both series meet AEC-Q100 grade one standards and include multiple protection circuits required for automotive systems.

Specifically, the BD5310xG-CZ provides unipolar detection, while the BD5410xG-CZ is designed for latch-type detection. The complete range includes 11 models that detect magnetic flux densities from 2.0 to 28.0mT. Unipolar detection is ideal for position sensing in systems like door open-close and door locks. In contrast, latch detection is better suited for rotation sensing in motors used in windows, sliding doors, and similar applications.
