What if you could fit better performance in a smaller space? Discover how this new Hall element improves camera stability and precision while reducing size.
Asahi Kasei Microdevices (AKM) has started mass production and shipment of its next-generation InAs (indium arsenide) compound Hall element, the HQ0A11. It features AKM’s smallest package size for an InAs-based Hall element, measuring 0.8 x 0.4 x 0.23 mm. This represents an 85% reduction in volume compared to the previous HQ0811 model in the HQ series. The HQ0A11 is expected to improve performance in smartphone camera modules, tiny robots, and other applications.
Hall elements are used for position detection in smartphone cameras for image stabilization and autofocus. As camera functionality improves and the need for higher-resolution capture grows, the demand for more components within the same or smaller form factor increases. This creates a need for compact products that enable high-density component mounting in limited space.
The HQ0A11 offers the highest S/N performance among AKM products for position detection by utilizing InAs. Its position detection accuracy is 3.5 times higher than the HG0C11, a GaAs (gallium arsenide) Hall element used in camera modules. The HQ0A11 helps reduce lens-shake effects, especially with telephoto lenses in smartphone cameras.
The company will continue to use its proprietary compound semiconductor and packaging technology to support the miniaturization and improved performance of electronic products, including smartphones, small motors for robots, and other applications.
The Hall element features AKM’s smallest and thinnest package size of 0.8 x 0.4 x 0.23 mm, offering increased flexibility in design for applications with limited space for mounting, such as smartphone camera and lens modules.
Its S/N performance is 3.5 times higher than the HG0C11 Hall element, the current mainstay product for camera modules. The HQ0A11’s high sensitivity also makes it suitable for applications like paper thickness detection.
The Hall element does not contain magnetic materials, reducing the risk of failure or malfunction due to adsorption or changes in magnetic field strength. This ensures stable operation even in environments near motors.
