Automotive Hall ICs have high voltage tolerance

Two series of Hall effect ICs from Rohm have a withstand voltage of 42 V, enabling direct connection to a vehicle’s primary 12-V battery power supply. High withstand voltage contributes to improved reliability under battery power, which can fluctuate rapidly depending on the operating conditions.

Intended for automotive applications requiring magnetic detection, the BD5310xG-CZ series provides unipolar detection, while the BD5410xG-CZ series offers latch-type detection. Both series are AEC-Q100 Grade 1 qualified and have a wide operating supply voltage range of 2.7 V to 38 V.

A total of eleven models span detection magnetic flux densities ranging from 2.0 mT to 28.0 mT. Unipolar detection can be used for detecting position in applications such as vehicle door open/close and door locks. Latch detection is useful for detecting rotation in various motors used for power windows and sliding doors.

The automotive Hall ICs are housed in SSOP3A packages and operate over a temperature range of -40°C to +150°C. Devices are available through Rohm’s distributor network.
