TLx5012B 2go Evaluation Kit

General description

1.2

Hardware description

The evaluation kit hardware is built around the XMC1100 Infineon target microcontroller (4), ARM M0 based.

In addition, the hardware includes an on-board debugger microcontroller (5) implemented with the Infineon

XMC4200 running a SEGGER Jlink debugger.

The sensor supply is ensured by a TLE4250-2G tracker (3) dynamically enabled / disabled by the target

microcontroller.

Two MOS transistors (2) - one PMOS and one NMOS - are being used for enabling a pull-up resistor (2.2 kΩ) and

for pulling down the line for the SPC pulse generation. Both transistors are controlled by the XMC1100 target.

The sensor (1) is placed on a break-apart region of the PCB so it can be removed and placed in a system.

For the connection to the PC a micro-USB (6) to USB cable is required (not provided with the package).
