EasyPoint™ AS5011

Description

The AS5011 is a complete Hall sensor IC for smart joystick module 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 integration complex SW algorithms on their host processor thus leading to rapid development cycles.

The AS5011 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 position and magnetic field information for each Hall sensor element is transmitted over a 2-wire I²C compatible interface to the host processor.

The AS5011 is available in 2 small 16-pin QFN packages (5x5x0.55mm / 4x4x0.55mm) and specified over an operating temperature of -20° to +80°C.

Our AS5011 is the driving technology behind EasyPoint™ module concept. This concept is based on contact-less, magnetic movement detection. Learn more about the simple use of EasyPoint™ in our demonstration video:
