Figure 1 Block diagram
The TLE92108 APPKIT board provides a simple, easy-to-use tool to get familiar with Infineon's Multi MOSFET
Driver TLE92108-232QX (TLE92108).
It contains the TLE92108 and a typical application circuit including 8 MOSFET half-bridges to drive up to 8 DC
motors. The board is ready to be connected to a vehicle level power supply and is controlled over SPI.
All pins relevant to control the device can be accessed via the dedicated 8 × 2 header using the uIO-stick by
hitex EMBEDDED TOOLS & SOLUTIONS (http://www.hitex.com/uIO).
The board is powered by the power connector and provides an active on-board reverse-polarity protection for
fastest response time in case of reverse polarity with minimal power-loss during normal operation.
The board allows control of Phase 1-8 which can be used to control up to 8 motors independently that can be
connected to OUT1-8 with the 4 screw terminal block motor connectors.
2 high-side shunts provide load current measurement and monitoring.

9 How to use the GUI (examples)
9.1 Example - PWM DC motor control using half-bridge 1 and 2
In this example a DC motor will be controlled by half-bridge 1 and 2. The half-bridge 1 output will be configured
for 20 kHz PWM with 50% DC and the load current can be monitored using CSA1.
Setup
Before you configure the GUI you will need to:
• Connect a DC motor to OUT1 and OUT2.
• Establish communication between the Appkit and the GUI as described in Establishing communication.
Configure the GUI

Figure 13 Control your first DC motor
To start the motor you will need to:
1. Set PWM 1 to 20 kHz and 50% DC (default values).
2. Map PWM 1 to HB1.
3. CSA1/2 are on and CSA 1 is selected by default. The PCB on-board jumper should connect CSO1 and
CSO1/2 as described in Current Sense Output (CSO) jumper setting. For correct current sensing the
value of RSHUNT should be set to 5 mΩ to match the PCB hardware.
4. Set Motor 1 to HS1/LS2 on.
The motor should start running with 20 kHz HS PWM at 50%.
The output of CSO1 can be seen in the CSA window (3).
