Concept Figure 1: Board Concept This board provides a simple, easy-to-use tool for getting familiar with Infineon’s Embedded Power IC TLE9879QXA40 (further to be named: TLE9879). It contains the TLE9879 and its typical application circuit including three MOSFET half bridges to drive a BLDC motor. The board is ready to connect with car supply or similar and has an onboard J-Link debugger. -
Page 4: Interconnects
The three pins of the terminal block provide access to the three half bridges and are intended to connect a DC brushless motor. USB for UART and Debugging (marked green) With this Micro USB PC and evaluation board can get connected. TLE9879 EvalKit V1.4 User Manual... - Page 5 For the uIO bootstrap loader an 8 pin header (2 x 4) with 2.54 mm pitch is placed on the board. It is intended to connect additional hardware for bootstrap loading. This uIO interface can be used to program the TLE9879 via LIN (see www.infineon.com/uio). RESET...
