Concept

1Concept

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

3Test 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.

Close this jumper to connect RESET button to RESET input. Open it to disconnect RESET

button from RESET input.

JP10

Close this jumper to connect an additional 1 kΩ pull-up resistor. This is intended for LIN

master communication. Open the jumper to use the TLE986x as slave in a LIN network.

Software for LIN low level driver can be found at the homepage of IHR (www.ihr.de).

JP12

Close this jumper to enable UART communication.

JP13

This jumper is closed by default. If this jumper is left open the device is not supplied. It is

intended to open the VSD line in order to measure the current flowing into the TLE986x

device.

Communication interfaces

5Communication 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).
