L298N output voltage problem [Copy link]

Is STMicroelectronics' L298N motor driver chip a constant voltage? Why does the output voltage of L298N vary when the motor load is different when I drive a DC motor? The greater the motor load, the smaller the output voltage of L298N. This content was originally created by EEWORLD forum user 992458448.

Of course, any driver has driving capability. The internal output is not a perfect 0 ohm, but also has switch resistance. It is the switch resistance that causes the voltage to be divided when driving a large load, so the output voltage you see is low.

First, find out the load size of the drive motor, or the power supply is not enough.
