Hi Team,
There are 5 DRV8872 on the control board, each of which controls a DC motor. The rated power of the motor is 36W, it is powered by 24V, and the current limit of DRV8872 is 1.75A. The power of the switching power supply is 240W. The customer encountered the following problem:
If the two motors enter the running state from the brake state at the same time, the switching power supply will be protected.
If one motor enters the running state from the brake, there is no problem.
If the two motors enter the coasting state from the braking state at the same time, and then enter the running state, there is no problem.
Customer would like to know what caused this? Or what are the precautions for using DRV8872 to drive the motor?
Thanks,
Annie
