Concept

1 Concept

Figure 2 PN Applikation Kit Concept

The TLE9845_App_Kit_PN provides an application near circuit to evaluate unidirectional DC motors. The
active PN-halfbridge can be used to evaluate motor connected to GND applications.

The TLE9845QX device is placed underneath the DC-link capacitor. The board is protected against reverse
polarity of input voltage supply.

A PN-channel MOSFET halfbridge is connected to the integrated highside and lowside switches of the
TLE9845QX Device.

In addition a highside current sense resistor is placed with an external operational amplifier.
It is connected to the ADC1 (P2.3).

The Application Kit provides a breakable On-Board debugger. It provides a SWD-Debug connection and a
virtual COM port for serial UART communication.

Power supply and motor connectors are accessable via plated through hole contacts, which can be used to
place M2.5 pressnuts (optionally).

Board features:

• Application near circuit (Motor connected to GND)

• Overcurrent Protection (external highside Shunt)

• Drain-Source-Monitoring (Differential Unit)

• USB-Communication and Debug-Interface (USB-Connector)

• Demo-Application Code and Graphical User Interface (GUI)

•LIN-PWM Example Code (PWM Genrator with GUI)

Figure 3 Interconnections Overview

2.5mm Screw Nut Connectors
Ground, voltagesupply (operating Voltage is documented in the datasheet) can be connected via 2.5mm

Screw Nuts.
Motor contacts can also be accessed with 2.5mm screws. MOTOR(+) has a seperate connector. MOTOR(-) is
shared with the GND connector.

LIN/PWM Connector
This connector is a direct access to the LIN/PWM Interface of the TLE9845QX. After Breaking the Debug-

Interface. BSL-Mode can be used to perform programm updates via LIN Interface Chapter 3.

USB
An Onboard-debugger is implemented on the TLE9845QX Appkit. The USB-Connection provides a Debug- and
Serial-interface to the PC. More information in Chapter 3.3.

SWD Interface
The SWD PIN-Header can be used optionally, instead of using the On-Board Debug Interface.

Communication Interfaces

3 Communication Interfaces

3.1 LIN and uIO for LIN BSL

The device integrated LIN transceiver is connected to a dedicated Connector (see Figure 3). To integrate the
device in a LIN network it is sufficient to use the single wire banana interface. The BSL interface is intended to
program the device via LIN. For further information about the uIO interface see www.hitex.com/uio.

3.2 UART (Virtual COM PORT via USB)

A virtual COM port provided by Segger driver enables a PC – board – communication via UART. The UART2
module of TLE9845QX uses the pins P1.0 (transmit) and P1.1 (receive). Those are connected to the XMC4200,
which emulates Rx and Tx on PC side with Segger firmware. Though they can be disconnected physically,
bidirectional level shifters ensure that the XMC pins are hi-Z in case the virtual COM port is not used. By
connecting the evaluation board to the PC a virtual COM port gets emulated by the Segger driver
automatically. The virtual COM port will show up in the Microsoft® Windows® device manager.

Figure 4 UART and Debugging

Note: Only one of the interfaces USB or SWD can be used at one time. While using the SWD interface the XMC is

ho ld i n re set. As l ong as a d ebu gge r is c onn ect ed wi th the SWD interface it eliminates therefore debugging
or UART via USB.

3.3 SWD-Debuginterface (J-Link via USB)

For serial wire debug the TLE984x uses the pins TMS (data) and P0.0 (clock). Level shifters between XMC4200
and TLE9845QX allow using P0.0, while it is not used for debugging.

The Segger J-Link module on board allows serial wire debugging via USB. Alternative debugging via SWD
interface is possible to debug with another ISP than the onboard Segger e.g. U-Link2. Therefore the signals are
routed through the 10 pin header SWD interface between the XMC4200 and the TLE984x. The pin configuration
makes sure that the XMC is hold in reset while another debugger is physically connected to X11. The virtual
COM port will be disabled, while the external ISP is connected.

Software Toolchain

4 Software Toolchain

4.1 Keil µVision 5

The recommended Integrated Software Developement Environment is Keil® µVision5®. Infineons embedded
Power family is suported. For more information about the Toolchain go to: www.keil.com

4.2 Infineon Config Wizard

In addition to the IDE, Infineon® provides the ConfigWizard. The tool is designed for code configuration, in
combination with the IDE. Infineons Config Wizard can be downloaded via:

www.infineon.com/embeddedpower

4.3 TLE9845QX Installation

All embedded Power products can be installed to Keil® µVision5® via “Pack Installer”. Browsing to the Infineon
chapter in “All Devices” will lead to the “TLE98xx Series”. The “.pack” file comes with several code examples,
to provide an easy start up and speed up software developement.

4.4 Debug Connection Setup

For a proper Flash and Debug Connection, Install V5.10 (or newer) from: www.segger.com/jlink-software.html
Keil® µVision5® has to be configured in the IDE Menu “Options for Target”. After connecting the USB-cable and

power up the Evalboard, go to the “Debug” register-card and choose “J-LINK / J-TRACE Cortex” and press
”Settings”.

Figure 5 Debug and Flash Configuration

If the board has been connected successfully, the ARM IDCODE will be visible in the SW Device Window.
If connection fails, “Connect & Reset Options” and “Port” window has to be checked.
