Low-power integrated Hall IC suits human interface apps

Designed for any kind of 360° navigation input device requiring low power,the highly integrated AS5013 Hall sensor IC is a contactless magnetic encoder device 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 I2 C interface. Due to the onchip processing engine, system designers are not tasked with integrating complex software algoritms on their host processor thus leading to rapid development cycles.

This single-chip IC includes user-selectable power-saving modes, five integrated Hall sensing elements for detecting up to ±2-mm lateral displacement, a high-resolution A/D converter, an XY coordinate and motion detection engine, and a smart power management controller. The HMI device also provides 2 interrupt modes (motion detect, data ready) and two 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 IC is offered in a 16-pin 4 x 4 x 0.55-mm QFN package. ($2.92 ea/1,000 — available now.)
