I'm using TMC2130 for a drive a stepper motor that has 1A phase current. While driver is enabled (not spinning), it get heated too high. what is the problem ? How can I avoid heating ?
Thank in advance
The mosfet of TMC2130 is inside the chip , and the max RMS is 1.2A , so it will be very hot. According to our test , sometime it heat up to 80 degree. You need a heat sink on the chip and a cooling fan to cool it down.
