Concept
1 Concept
Figure 1 Board concept
This board is designed to provide a simple, easy-to-use tool for getting familiar with Infineon’s Embedded Power IC TLE986x devices. A socket provides the possibility to test and evaluate all ICs of the TLE986x family. Every pin of the IC is connectable via rows of pin headers. The board is protected against reverse polarity of input voltage supply.
Two MOSFET half bridges are assembled on the board to drive a DC motor. The board is ready to be connected to a car supply or similar and offers a SWD port to connect an external debugger.
The evaluation board can be operated by standard laboratory equipment as power supply and LIN communication are working via banana jacks.
There is a battery LED that indicates that the board is connected to supply in the correct way. Otherwise reverse polarity protection secures the board from damage by cross connection.

Figure 2 Interconnects
Banana jacks for ground, supply and LIN
There are jacks in different colors for ground, supply (max. 28 V) and LIN communication via banana jack. The following jacks are available: GND (marked purple), VBAT (marked red), motor phase 1 & 2 (marked red) and LIN (marked green).
Banana jacks for motor connection (marked red)
The two jacks Phase1 and Phase2 provide access to the two half bridges and are intended to connect a motor.
uIO Stick connector (marked green)
This uIO bootstrap loader is a 16-pin header (2 x 8) with 2.54 mm pitch.
It is intended to connect additional hardware for bootstrap loading. This interface can be used to program the TLE986x via LIN (see www.infineon.com/uio or www.hitex.com/uio).

Test points and LEDs
3 Test points and LEDs
Figure 5 Test points
Several ground test points are provided.
Test point LIN_INT is used to measure the LIN voltage.
Test point VDH is used to measure the voltage on the VDH pin.
Tests points Motor 1 and Motor 2 can be used to measure the voltage at phase 1 and 2 of the motor.
There are 11 LEDs for visual validations on the board:
LED 1 to 8 can be connected to GPIOs (see Table 3). LED 9 (Vbat LED) indicates power supply. LED 10 (Motor Status 1) lights up if the motor is running forward. LED 11 (Motor Status 2) lights up if the motor is running backward.

Communication interfaces
5 Communication interfaces
5.1 LIN (via banana jack and uIO BSL)
The device integrated LIN transceiver is connected to a banana jack and additionally to the uIO BSL interface. 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.infineon.com/uio or www.hitex.com/uio.
5.2 UART
A RS232 connector on the board enables a serial communication.
5.3 Debugging
Debugging is possible via the SWD interface; the signals are routed through the 10 pin header SWD interface (see Figure 4).
