ON Semiconductor Introduces All-in-One Auto Focus Controller for Smartphone Camera Modules

ON Semiconductor (Nasdaq: ONNN), driving energy efficiency innovations, has introduced the LC898214XC Auto Focus Controller for camera modules in smartphones.

This integrated solution features digital loop filter and provides fast, accurate auto focus convergence with temperature compensation, while consuming minimal power. The integrated constant current driver provides lower electro interference noise than competing solutions. In addition, the space-saving design enables thinner and lighter smartphones.

“There is a strong and growing demand for improved smartphone camera features – specifically for fast, accurate, power-friendly auto-focus,” said Ikuya Kawasaki, general manager of the Intelligent Power Solution division at ON Semiconductor. “We developed this highly integrated, all-in-one auto focus controller for the specific demands of smartphone applications. The market demands higher performance auto focusing, with low power consumption and small size. The LC898214 provides the desired accuracy with a closed auto focus system.”

LC898214XC integrates all functions for the closed auto focus driver, including digital logic as a closed auto focus control, Hall device as a positioning sensor, EEPROM for the storage of filter parameters and compensation data, and a constant current driver as an actuator driver. The closed auto focus system provides for more accurate auto focus control, while also lowering power consumption compared with open loop systems. The loop filter coefficients are adjustable via an I2C interface, allowing the device to be programmed for optimal convergence time when paired with various different actuators. These integrated features support a closed auto focus system, and can provide higher auto focus performance from one integrated circuit.

Packaging and Pricing

LC898214XC is offered housed in a Pb-free, Halide-free WLCSP-8 package and is priced at $0.88 USD per unit in quantities for 4,000 units.

When an enterprise builds a hybrid IaaS cloud connecting its data center to one or more public clouds, security is often a major topic along with the other challenges involved. Security is closely intertwined with the networking choices made for the hybrid cloud. Traditional networking approaches for building a hybrid cloud try to kludge together the enterprise infrastructure with the public cloud. Consequently this approach requires risky, deep "surgery" including changes to firewalls, subnets...

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric.

This last trend is the IoT stack, which involves a new shift in the separation of what stuff happe...
