austriamicrosystems Presents Hall Sensor IC AS5510 for Mobile Electronic Systems

austriamicrosystems, a pioneer in the designing and fabrication of standard analog ICs, has released a linear Hall sensing IC called the AS5510 with a miniature size and a resolution of ten-bit digital display. The device is enclosed in a minute 1.46 mm x 1.1 mm chip module and consists of an I²C dual-wire serial connection for varying between four non-identical flexibility ranges and for easier communication of information to a microcontroller.

The AS5510 is configured in such a way as to satisfy the consumer requirements meeting the size, characteristics and quality needed for non-contact linear monitoring of positions such as in the locked-loop position controlling devices with self-focusing or zooming imaging systems. The sensor is capable of calibrating accurate position of a non-complex dual-pole magnet with a lateral stroke of 0.5mm to 2 mm having air gaps of 1.0 mm. By employing robust magnets even higher air gaps and lateral strokes can be achieved.

The AS5510 will automatically turn to a power-down of 25 µA functionality so as to lower the power utility. The I²C connection gives an easy and speedy interface to the microcontroller eliminating the requirement of an analog to digital transition. All these characteristics make the deployment of these sensors in mobile electronic devices efficient.

Alfred Binder, Marketing Manager, HMI devices, austriamicrosystems recounted that the extended range of integration of the AS5510 reduces the complexity and prevents issues related to gain, noise and reference voltages.

The linear Hall sensor is operative over -30°C to +85°C thermal range and is available in a six-pin WLCSP with a 2.5V to 3.6V voltage functionality.
