AS5013
Low Power Integrated Hall IC for Human Interface Applications
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
transmitted over a 2-wire I²C compliant interface to
the host processor.
The
4x4x0.55mm QFN package and specified over an
operating temperature of
-20 to +80°C.

... The movement of the magnet over the Hall elements causes response which is geometrically distributed like a bell- shaped curve. The maximum magnet travel is a circle of 2mm radius around the center of the AS5013. The hall elements C1..C4 are placed on a circle centered on the middle of the package. The hall element C5, placed exactly in the middle is used for better linearity response with magnet displacement larger than +-1 ...

... Transfer function AS5013 has the possibility to adjust the transfer function for the used magnet and a specific range to optimize the linearity and resolution. The value will be provided from austriamicrosystems AG and has to be written in the algorithm related registers M_ctrl [0x2B], J_ctrl [0x2C], T_ctrl [0x2D] during the initialization phase. ...

... After power up and after applying a soft reset (Reg 0Fh [1]) or hardware reset (RESETn input, LOW pulse >100ns), AS5013 enters the START-UP state. During this state the internal registers are loaded with their reset values. After min. Tstartup = 1000µs, the AS5013 will perform one measurement and switches automatically into the WAIT state. ...

... It is possible that this value cannot be reached with small magnets or with large airgaps. In that case set AGC to 3Fh, which is the maximum sensitivity. 3.14 Power ON The AS5013 has a Power ON Reset (POR) cell to monitor the VDD voltage at startup and reset all the internal registers. After the internal reset is completed, the POR cell is disabled in order to save current during normal operation. ...

... Data Sheet 4.4 I²C modes The AS5013 supports the I2C bus protocol. A device that sends data onto the bus is defined as a transmitter and a device receiving data as a receiver. The device that controls the message is called a master. The devices that are controlled by the master are referred to as slaves. A master device that generates the serial clock (SCL), controls the bus access, and generates the START and STOP conditions must control the bus. The AS5013 operates as a slave on the I² ...
