ROHM’s New Automotive-Grade High Voltage Hall ICs BD5310xG-CZ / BD5410xG-CZ Series Feature an 42V Withstand Voltage
ROHM has developed Hall ICs, the BD5310xG-CZ / BD5410xG-CZ series, designed for automotive applications requiring magnetic detection.
In recent years, the continuing computerization of vehicle systems to meet the demand for increasing electrification and functionality along with greater comfort and safety has required additional ECUs (Electronic Control Units) and sensors to provide control.
Among these sensors, Hall ICs are becoming one of the most adopted types due to their ability to detect position and motor rotation in a non-contact manner that reduces the wear-and-tear prevalent with mechanical switches while also being compact and can be equipped with protection circuits.
ROHM has developed Hall ICs for automotive applications that improve reliability by combining Hall IC expertise cultivated over many years for the mobile and consumer sectors with original high withstand voltage processes. As a result, the BD5310xG-CZ / BD5410xG-CZ series features an industry-leading 42V withstand voltage that enables direct connection to a primary (12V battery) power supply. This contributes to improved reliability under battery power, which can fluctuate rapidly depending on the operating conditions. At the same time, a wide operating supply voltage range of 2.7V to 38V enables support for a variety of applications. The unique internal topology also reduces power consumption by approx. 20% over general products to achieve an industry-leading current consumption of 1.9mA. Both series comply with the AEC-Q100 (Grade 1) automotive reliability standard while incorporating multiple protection circuits required for vehicle systems.
The BD5310xG-CZ series is a unipolar detection type while the BD5410xG-CZ series provides latch-type detection, giving designers the flexibility to select the ideal product based on set needs. A total of 11 models are offered in detection magnetic flux densities - ranging from 2.0mT to 28.0mT. Unipolar detection can be used for detecting position in applications such as door opening/closing and door locks, whereas latch detection is ideal for rotation detection in various motors used in power windows, sliding doors, and the like.
Going forward, ROHM will continue to expand its lineup of sensor ICs that contribute to higher reliability and functionality in automotive applications.

【经验】罗姆RPR-0521RS环境光接近传感器在开发板上运行Arduino例程出现错误解决方法
RPR-0521RS环境光接近传感器搭配开发板SENSORSHIELD-EVK-003使用，官方提供的例程是Ardunio平台的。如果打开文件出现错误信息“RPR-0521RS.h：No such file or directory”如何解决？
Only TMR Current Sensors Can Enable Efficient Industrial and Automotive Applications
Today, a wide variety of industrial and automotive applications are demanding higher efficiency which impacts many design decisions including the current sensing requirements. The demands are so dramatic that it may be that existing magnetic-based solutions will be obsolete by 2030. These applications demand wide band gap (WBG) power devices pushing the performance requirements for current sensing.
