AS5013
Low Power Integrated Hall IC for Human Interface Applications
1 General Description
The AS5013 is a complete Hall Sensor IC for smart navigation key applications to meet the low power requirements and host SW integration challenges for products such as cell phones and smart handheld devices. Due to the on chip processing engine, system designers are not tasked with integrating complex SW algorithms on their host processor thus leading to rapid development cycles. The AS5013 single-chip IC includes 5 integrated Hall sensing elements for detecting up to ±2mm lateral displacement, high resolution ADC, XY coordinate and motion detection engine combined with a smart power management controller. The X and Y positions coordinates and magnetic field information for each Hall sensor element is transmitted over a 2-wire I²C compliant interface to the host processor. The AS5013 is available in a small 16-pin 4x4x0.55mm QFN package and specified over an operating temperature of -20ºC to +80ºC.
