    Hello, I wanted to ask for help with my project. I wanted to increase the supply voltage of the wiper motors from 12 to 24V the BTS7960 H-bridge 43A. The problem is that the bridge does not work properly on 24V. Everything works fine on 12V, but at 24V the bridge freezes the USB port, as if it is increasing the voltage on the control logic from Arduino or generates noise and this blocks the port (what you can hear is that at 24V the motor makes an oscillating sound, and when the motor is disconnected it is also quieter in the computer, at 12V you can't hear anything, the simtool is connected and controls the movement correctly, after increasing the voltage to 24V the computer gives a signal to disconnect the USB and Simtool closes, even the mouse stops-crasched)
