December 13, 2010 - austriamicrosystems announced the AS5013, a contactless magnetic encoder IC that monitors the displacement of a magnet incorporated in a knob relative to its center position and provides x and y position information via an I²C interface. The AS5013 Hall-sensor IC is used in the EasyPoint mini joystick module, which consists of a mechanical stack incorporating a navigation knob, a magnet and the AS5013 magnetic encoder IC. Its simple construction and contactless sensing technology give the module very high reliability and is designed for any kind of 360° navigation input device. The AS5013 is a complete Hall-sensor IC for human-machine interface (HMI) applications requiring low power.
This simplifies software integration challenges for joystick navigation in products such as remote controls. The AS5013 single-chip IC includes user-selectable power-saving modes, 5 integrated Hall sensing elements for detecting up to ±2 mm lateral displacement, a high-resolution analog-to-digital converter (ADC), an XY coordinate and motion detection engine, and a smart power management controller. The XY coordinate registers and magnetic field information for each Hall-sensor element are transmitted over the I²C interface to the host processor. The HMI device also provides 2 interrupt modes (motion detect, data ready) and 2 operating modes: idle mode, with less than 3 µA current consumption, and low-power mode, with selectable readout rate.
The low-power AS5013 operates over a power supply range of 2.7 to 3.6 V, and down to 1.7 V peripheral supply voltage.Specified over an operating temperature of -20 to +80°C, the AS5013 Hall-sensor IC operates from a 3.3 V power supply and is offered in a 16-pin 4 x 4 x 0.55 mm QFN package.
The EasyPoint module is available as small as 8 x 8 x 1.5 mm.
Price & Availability
The AS5013 contactless magnetic encoder IC is available now and costs $2.92 in 1000 piece quantities.
