Figure 2 TLE985x Evaluation Board concept

This board is designed to provide a fast and easy start of evaluation for Infineon’s Embedded Power TLE985x
device family. Initialy, the evaluation board brings several interfaces and interconnections shown in Figure 2.

The TLE985x device is placed in the center of the PCB. A socket provides the possibility to test and evaluate all ICs
out of the TLE985x device 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 available to instantly drive a DC motor, which can be connected via banana jacks.
The evaluation board provides an on-board debugger. It is placed in the lower right of Figure 2. It provides a

debug connection (SWD) and a virtual COM port for serial UART communication.
The high-voltage monitor pins can be triggered with dedicated pushbuttons.
For analog input values, a potentiometer is connected to pin P2.1.
The LIN connection can be configured to master or slave mode.

4mm laboratory connectors (orange)

Ground, supply voltage (operating voltage is documented in the datasheet) and LIN communication can be
connected via banana jacks:
GND (black), VBAT (red), LIN (green)

Two MOSFET half bridges can also be accessed with laboratory equipment:
PHASE1 and PHASE2 (green)

uIO connector (purple)

The uIO Stick can be connected at the upper right corner of the evaluation board. It provides BSL programming
via FastLIN. The connector provides a reverse-polarity protected connection between the evaluation board and
the uIO Stick. (Signals: RESET, VS, LIN)

USB (black)

An on-board debugger is implemented on the TLE985x Evaluation Board. The USB connection provides a debug
and serial interface to the PC.

Pin headers (red)

Each pin of the TLE985x is available for measurements and evaluation via pin headers.

Figure 4 Jumper settings

Figure 4 shows the jumper positions on the Evaluation Board. The colors give an information about the voltage,

which can appear at the jumper pins as follows:

• Green-marked jumpers are related to the 5-V domain (voltage range 0 V ... VDDP/VDDEXT).

• Blue-marked jumpers are related to high-voltage inputs or outputs of the TLE985x.

• Purple-marked jumpers are connected to the supply voltage of the evaluation board.

Table 1 shows which jumper is connected to which pins and peripherals of the TLE985x.
