Revision 1.11
1 - 32
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 ?mm 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 I睠 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
-20篊 to +80篊.
