The programmer board typically draws about 350 mA when connected to the TLE4972 evaluation boards. This
current can be delivered via the USB port of a PC, which is usually specified to deliver up to 500 mA. A reverse
current protection diode ensures safe operation and protects the USB port of the Laptop/PC in case power is
provided through the measurement header at the same time.
In
Chapter 3.2 it is shown an optional power supply plug to provide a connection to an external power supply in
case the USB connection can't support the power requirement of the programmer board.
