  • Page 3: Concept

    The TLE9844-2QX Appkit provides an application near circuit to evaluate relay based bidirectional dc motor applications. The TLE9844-2QX device is placed near a 2-Channel Relay. The board is protected against reverse polarity of input voltage supply. GPIOs, high voltage monitor PINs and high side switches are accessible via pin head connectors.

  • Page 4: Interconnections

    These Pins are capable to measure voltages on battery voltage level, directly. The second Pin head row is connected to GND. Analog Pins The 5V Analog Channels of the TLE9844-2QX can be accessed at this pin row. Their name suffix is P2.x. TLE9844-2QX Application Kit User’s Manual Rev. 1.0...
  • Page 5 For operating the relay, a 12V supply is mandatory. LIN Interface This connector is a direct access to the LIN Interface of the TLE9844-2QX. The LIN Interface can be used to establish halfduplex connections to other boards or modules for evaluation. The example code library provides example projects for LIN master and slave low level drivers.

  • Page 6: Communication Interfaces

    A virtual COM port provided by Segger driver enables a PC – board – communication via UART. The UART2 module of TLE9844-2QX uses the pins P1.0 (transmit) and P1.1 (receive). Those are connected to the XMC4200, which emulates Rx and Tx on PC side with Segger firmware. Though they can be disconnected physically, bidirectional level shifters ensure that the XMC pins are hi-Z in case the virtual COM port is not used.
