1 Concept
Figure 1: Board Concept
This board is intended to provide a simple, easy-to-use tool for getting familiar with Infineon’s embedded power IC TLE9869. It contains the TLE9869 and its typical application circuit including two MOSFET half bridges to instantly drive a DC motor. The board is ready to connect with car supply or similar and has an implemented Segger for debugging on board. All relevant chip pins are connected to pin headers at the edge of the board, where signals can be probed or applied directly (see Table 2, Table 3). By different jumper settings LEDs can be put in parallel to several ports and selected functions can be configured (see Table 6). Push button switches allow easy hardware reset and triggering of the MON input. There are intended test points for all four gate driver pins, for measurements at the shunt, VDDC and several ground points on the evaluation board (see Figure 3). For testing analog signals ADC inputs can be varied by the potentiometer on board. Two phases of motor current can be picked off at a terminal block to connect a DC motor. The evaluation board can be operated by standard laboratory equipment as power supply and LIN communication are working via banana jacks. Debugging and UART are provided via an USB interface combined with onboard Segger J-Link (XMC4200). Bidirectional level shifters ensure that the respective XMC pins are in tristate as long as UART or debugging is not used. In case the user wants to use another ISP than the onboard Segger the SWD interface can be used. To program the TLE9869 via LIN there is an additional uIO BSL interface (see Table 4). There is a battery LED that indicates that the board is connected to supply the right way. Otherwise reverse polarity protection secures the board from damage by cross connection.

Banana jacks (marked yellow)
There are jacks in different colors for ground, supply (max.28V) and LIN communication via banana jack: GND (black), VBAT (red), LIN (green)
Pin Ports X4 and X5 (marked red) Soldering pin headers with 2,54mm pitch for X4 (1x10) and X5(1x16) yields test points for the TLE9869 pins. Following signals are connected to the pins:

uIO BSL for LIN (marked orange) This uIO bootstrap loader is an 8 pin header (2x4) with 2,54mm pitch. It is intended to connect additional hardware for bootstrap loading. For programming the TLE9869 via LIN this uIO interface can be used (see www.infineon.com/uio).

Pin Header for SWD (marked purple)
There is a 10 pin header (2x5) with 1,27mm pitch on the evaluation board. For debugging with another ISP than the onboard Segger this interface can be used. DBPRE will be implicitly connected to GND by connecting the external ISP. This keeps the XMC in reset state to prevent interference of the SWD communication.
