Tech Expert

Diodes Inc.'s new AH332xQ and AH352xQ Hall effect switch ICs represent a significant advancement in automotive proximity sensing technology. The wide range of switching sensitivities (from 30G to 275G for unipolar and ±20G to ±40G for omnipolar) allows for precise calibration in various automotive applications. This flexibility is important for optimizing sensor placement and performance in tight spaces.

The wide operating voltage range (3.0V to 28V) and temperature range (-40°C to +150°C) are particularly noteworthy, as they ensure reliability in harsh automotive environments. The inclusion of protective features like reverse blocking diodes, Zener clamps and ESD protection up to 8kV HBM demonstrates a robust design that meets stringent automotive requirements.

At $0.30 per unit in volume, these ICs offer a cost-effective solution for automakers looking to enhance safety and convenience features across their vehicle lineup. The availability of multiple package options further supports design flexibility and easy integration into existing automotive systems.

Market Research Analyst

The introduction of these automotive-compliant Hall effect ICs positions Diodes Inc. favorably in the growing market for advanced driver assistance systems (ADAS) and vehicle safety features. The global automotive sensor market is projected to reach $40 billion by 2026, with a CAGR of 6.5%. Hall effect sensors play a important role in this growth, particularly in applications like seatbelt detection and door latching.

Diodes Inc.'s competitive pricing at $0.30 per unit in volume orders could help the company capture a larger market share, especially among mid-range vehicle manufacturers looking to add premium safety features at a competitive price point. The wide range of sensitivity options also allows Diodes Inc. to cater to various automotive design needs, potentially expanding their customer base within the industry.

Investors should note that while this product line enhancement is positive, its impact on Diodes Inc.'s overall financial performance may take time to materialize, as automotive design cycles are typically long.

PLANO, Texas--(BUSINESS WIRE)-- 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 (B_OP), and switches off when the flux density falls below the release threshold (B_RP). Ten sensitivity options are available, ranging from a highly sensitive 30G B_OP to a low-sensitivity 275G B_OP 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 B_OP and turns off when the magnetic flux density falls below the B_RP. Three high-sensitivity options are available, ranging from ±20G to ±40G B_OP devices.

The B_OP and B_RP 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.
