Rohm designs automotive-grade high voltage Hall ICs for magnetic detection
Two Hall ICs, the BD5310xG-CZ and BD5410xG-CZ series are designed for automotive applications requiring magnetic detection, advised Rohm Semiconductor.
Hall effect ICs are used for position detection and motor rotation functions in vehicle systems. They operate in a non-contact manner that reduces the wear and tear experienced by mechanical switches. They are also compact and can be equipped with protection circuits.
The BD5310xG-CZ and BD5410xG-CZ series feature what is claimed to be 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, said Rohm. They also have a wide operating supply voltage range of 2.7V to 38V. The topology is also claimed to reduce power consumption by approximately 20 per cent over general products for current consumption of 1.9mA. Both series of ICs comply with the AEC-Q100 (Grade 1) automotive reliability standard and also have multiple protection circuits required for vehicle systems.
The BD5310xG-CZ series is a unipolar detection type; the BD5410xG-CZ series provides latch type detection. There are a total of 11 models 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 windows and sliding doors.
Rohm Semiconductor develops and manufactures a large product range from SiC diodes and MOSFETs, analogue ICs such as gate drivers and power management ICs to power transistors and diodes to passive components. Production is in the company’s manufacturing plants in Japan, Germany, Korea, Malaysia, Thailand, the Philippines, and China.
Rohm Semiconductor Europe has its head office near Dusseldorf serving the EMEA region (Europe, Middle East, and Africa).
