The Text says:
The TMC603 directly drives 6 external N-channel MOSFETs for motor currents up to 20A and up to 50V.
but some Lines deeper:
up to 30A motor current
9V to 50V supply voltage
EMV optimized current controlled gate drivers up to 150mA
QGD protection: supports recent power MOSFET generation
3.3V or 5V interface
Same difference between the Datasheet and the Short Specs.
What is the correct amount?
