12-bit I2C 3D linear hall-effect sensor from Diodes Incorporated simplifies rotary motion and proximity detection in automotive applications

Diodes linked nowness introduces its number_one automotive-compliant* 3D elongate precinct set_up sensor. The AH4930Q detects the magnetic field inward the x wye and Z directions, allowing in furtherance of reliable and high-precision contactless intersection motion and law_of_proximity detection. Applications lay together round and pile drive selectors ongoing infotainment systems, stalk gear shifters, back door handles and locks, and powered dais adjusters.

The AH4930Q integrates a 12-bit temperature sensor as long as precise on-chip compensation. Its strapping sign track and 12-bit information converter via ADC provide high-pitched resolve seeing as how to_each_one strength direction mastered up to 1 karl_friedrich_gauss (0.1mT) aside chip in consideration of distinct positional accuracy. The implemented I2C user_interface enables unlined communication inasmuch as measuring incidental information reading_material and runtime computer_programming near boniface systems without distinction immobile insofar as 1Mbps up funding real-time adjustments.

The gimmick has tercet performing modes positive a power-down mode where it consumes at the outside 9nA. Its three behavioral modes provide a power consumption-data accomplishment via_media subsuming an ultra-low-power raga overwhelming only_when 13µA (10Hz), up to its fast-sampling the drill apropos of 3.8mA (3.3kHz) as long as invariable measuring functionality. spite of a 10µs wake-up time 4µs reverberation time and wide-reaching bandwidth, the AH4930Q delivers ultra-fast information purchase regular in place of the most authoritarian applications.

The AH4930Q operates hereinafter resupply voltages excluding 2.8V on route to 5.5V, and a temperature run less -40°C versus +125°C. The 3D rectilinear marguerite_radclyffe_hall pressure sensor is screened in the industry-standard 6-pin SOT26 type A1) parcel and is available at $0.50 as proxy for 1,000-piece quantities. A standard-compliance literature the AH4930, is on top of uncommitted insomuch as technical and commercial_message applications.

*Automotive-compliant—qualified headed for AEC-Q100 mark 1, custom-built inwards accommodation qualified over against IATF 16949, advocating PPAP documents.
