Laser Focus World is an industry bedrock—first published in 1965 and still going strong. We publish original articles about cutting-edge advances in lasers, optics, photonics, sensors, and quantum technologies, as well as test and measurement, and the shift currently underway to usher in the photonic integrated circuits, optical interconnects, and copackaged electronics and photonics to deliver the speed and efficiency essential for data centers of the future.

Our 80,000 qualified print subscribers—and 130,000 12-month engaged online audience—trust us to dive in and provide original journalism you won’t find elsewhere covering key emerging areas such as laser-driven inertial confinement fusion, lasers in space, integrated photonics, chipscale lasers, LiDAR, metasurfaces, high-energy laser weaponry, photonic crystals, and quantum computing/sensors/communications. We cover the innovations driving these markets.

Laser Focus World is part of Endeavor Business Media, a division of EndeavorB2B.

Automotive-Compliant, Hall Effect ICs from Diodes Incorporated Offer Wide Choice of Switching Sensitivities for Optimal Proximity Detection

Diodes Incorporated (Diodes) (Nasdaq: DIOD) announces the addition of two enhanced high-voltage, Hall effect switch IC families to its automotive-compliant* product portfolio. The AH332xQ (unipolar) and AH352xQ (omnipolar) offer a wide range of operating sensitivity options in SIP-3, SOT23 (Type S), and SC59 packages. The devices can be used in a broad range of contactless position and proximity detection applications, including seatbelt fastening, door and trunk latching, windshield wipers, and steering-wheel locks.

The unipolar AH332xQ is activated when the magnetic flux density of correct polarity exceeds the defined operating threshold (BOP), and switches off when the flux density falls below the release threshold (BRP). Ten sensitivity options are available, ranging from a highly sensitive 30G BOP to a low-sensitivity 275G BOP version, allowing for a wide range of magnet and distance choices for optimal sensing.

The omnipolar AH352xQ is activated when the magnetic flux density of either a magnetic south or north pole exceeds the BOP and turns off when the magnetic flux density falls below the BRP. Three high-sensitivity options are available, ranging from ±20G to ±40G BOP devices.

The BOP and BRP thresholds for both the AH332xQ and AH352xQ provide a tight operating window with sufficient hysteresis for reliable operation, while a low-temperature coefficient ensures the stability of the switching points.

The AH332xQ and AH352xQ Hall effect devices have an open-drain output and operate over a wide 3.0V to 28V supply voltage range and -40°C to +150°C temperature range, providing product design flexibility to meet the requirements of the harsh automotive environment. Even when physical stress is applied to the package, the devices maintain very accurate sensitivity levels. For enhanced robustness and reliability, the devices have reverse blocking diodes with Zener clamps on their supply pins, as well as overcurrent limits and Zener clamps on their open-drain output. ESD protection exceeds 8kV HBM and 1kV CDM, and the devices have a 40V load-dump capability.

The AH332xQ and AH352xQ are available at $0.30 in 3,000-piece quantities.
