ROHM Semiconductor today announced the BD5310xG-CZ / BD5410xG-CZ series of
Hall ICs 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 type 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 they 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[1] 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 approximately 20
percent 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 eleven 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 open/close 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.
