1 Introduction

Infineon’s 3D Magnetic Sensor 2 Go is a compact evaluation kit to familiarize the user with the 3D Hall sensor

TLE493D-A2B6. In a short time the board is set up and own 3D magnetic measurements can be executed. All

required hardware is included and the soware can be downloaded for free from the Infineon web page.

This user manual describes the dierent parts of the board, the soware installation process and clarifies how

the Graphical User Interface (GUI) can be used to do first evaluations.

1.1 Hardware overview

The 3D Magnetic Sensor 2 Go kit contains:

• The 3D evaluation board (EvalBoard) as shown in Figure 1, a ready-to-use printed circuit board (PCB) with

the 3D Hall sensor. The EvalBoard is based on the XMC2Go-Kit. More technical documents and detailed

description can be found at http://www.infineon.com/xmc2go.

• A standalone block magnet.

To use the 3D Magnetic Sensor 2 Go kit the user has to acquire a USB cable with a micro USB connection-end for

the EvalBoard side and a conventional USB connection for the PC side.

1.2 Soware

The required soware to run the kit can be found at the Infineon web site. For further information refer to the

chapter Soware installation.

The soware package contains:

• A Graphical User Interface (GUI) for the user sensor evaluation.

• Firmware to be flashed into the XMC microcontroller for the low level communication with the sensor.

• USB driver J-Link from Segger which is necessary to establish the USB connection.

This soware was designed to be used with Windows 7 and Windows 10. It is compatible with both 32-bit and

64-bit system types. Other versions may also work, but have not been tested.

The USB protocols capabilities are defined by the Segger driver. Versions USB 2.0 and USB 3.0 should be

compatible.

The EvalBoard with the TLE493D-A2B6 3D Hall sensor can be used with the GUI version 3.0.0 and onwards.

The GUI is used to enable a communication between the sensor and the PC. The user can configure the sensor

to operate in dierent modes. In those modes the update rate of the magnetic field measured (X, Y and Z

components) and current consumption vary.

1.3 Magnet heads

As described in Chapter 1.1, a standalone magnet is provided with the 3D Magnetic Sensor 2 Go kit. This can be

manually placed to a desired position and then the magnetic field can be measured in the three dimensions.

In addition, Infineon oers magnet heads which can be mounted on the EvalBoard. Currently two magnetic

heads are available, a joystick and a rotation knob.

2 EvalBoard description

The evaluation board (EvalBoard) is a ready-to-use printed circuit board (PCB) which contains:

• The 3D magnetic sensor TLE493D-A2B6. For the availability of 3D Magnetic Sensor 2 Go kits with dierent

sensor variants check the Infineon web page: https://www.infineon.com/cms/en/product/sensor/

magnetic-position-sensor/3d-magnetic-sensor/

• XMC1100 microcontroller based on ARM Cortex™-M0 at 48 MHz frequency connected to the 3D sensor.

• XMC4200 microcontroller based on ARM Cortex™-M4 at 144 MHz frequency used for the debugging and the

USB communication.

• Micro USB connector for power supply and communication with the Graphical User Interface (GUI).

• LED for indication of power supply and debugging.

• Two LEDs for user configuration.

• Voltage regulator, reverse current protection diode and ESD protection diode.

• Pin headers to access data lines (e.g. via oscilloscope, external microcontroller).

The dierent components and its location are shown in Figure 5. The 3D magnetic sensor can be separated

from the rest of the EvalBoard by cutting the break line.

Figure 5 Main components of the EvalBoard

2.1 Optional external power supply

The 3D Magnetic Sensor 2 Go EvalBoard is supplied via the USB cable. It is also possible to provide an external

power supply. If this is the case, a few considerations must be taken into account as described below.

The 3D Magnetic Sensor 2 Go EvalBoard must be supplied by external 5 Volt DC power supply connected to the

micro USB plug. The voltage regulator shis the voltage level to 3.3 V for the microcontrollers and the 3D

magnetic sensor. The Power & Debug LED indicates that the presence of the generated 3.3 V supply voltage.

Out of the box with the pre-programmed application and the on-board debugger in operation the EvalBoard

typically draws about 75 mA. This current can be delivered via the USB plug of a PC, which is specified to deliver

up to 500 mA. An on-board reverse current protection diode will ensure safe operation and protects the USB

port of the Laptop/PC in case power is provided through the pin header X1.

It is not recommended to apply an additional power supply to the VDD pin of X1 (3.3 V) when the board is

powered via USB, because the 3.3 V supply could drive against the on-board power supply. The VDD pin can be

used to power an external circuit. But care must be taken not to draw more current than 150 mA, which is the

maximum current the on-board voltage regulator can deliver. Aer power-up the Debug LED starts blinking. In

case there is connection to a PC with correctly installed drivers, the Debug LED will turn from blinking to

constant illumination.

2.2 Pin header connector

The pin headers X1 and X2 can be used to extend the evaluation board or to perform measurements on the

XMC1100. The order of pins available at X1 and X2 corresponds to the pinning schema of the XMC1100

microcontroller in the TSSOP-16 pin package. The pinning table is also printed onto the bottom side of the PCB

(depending on the version). The pin header X3 can be used to access directly the 3D magnetic sensor pins.
