Addressing the need for increased electrification, functionality, comfort and safety in automotive applications, electronic control units (ECUs) and sensors are growing in number, especially Hall IC sensors. These Hall ICs deliver position detection and motor rotation on a non-contact basis so there is less wear than with mechanical switches. In response to the demand, Rohm Semiconductor has developed the BD5310xG-CZ/BD5410xG-CZ series for automotive applications.

Rohm said the new Hall-effect ICs provide an industry-leading 42-V withstand voltage for direct connection to a 12-V battery power supply. Target applications include automotive door locks, seat position, seat belts, wiper motors, power windows and sliding doors.
The BD5310xG-CZ offers unipolar detection required in door open/close and door locks, while the BD5410xG-CZ provides latch-type detection necessary for various motors including those used in power windows and sliding doors.
The series features a wide operating supply range of 2.7 V to 38 V and an internal topology that reduces power consumption by approximately 20 percent for a current consumption of 1.9 mA.
Both series comply with the AEC-Q100 (Grade 1) automotive reliability standard and provide the protection circuits required in vehicle systems. Eleven models are available in detection magnetic flux densities from 2.0 mT to 28.0 mT.
