Tool/software:
Hi,
I have an application using DRV8876 in PH/EN Control Mode to drive a DC brushed motor with up to 100mA motor current.
PH/EN doesn't allow coast mode. Now I have seen in this e2e post (https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1112400/drv8251-question-about-brake-and-coast?tisearch=e2e-sitesearch&keymatch=coast#), that Coast mode is typically mechanically more gentle to the system because it isn't an abrupt stop.
Would you say that it should be fine for usual BDC motors to drive them using PWM signal for DRV8876 to permanently switch between forward drive and brake (low side slow decay) mode?
Or would you recommend using coast mode instead of brake mode? And can the body diodes of the DRV8876 integrated FETs handle the "free-wheeling" currents?
Thanks & BR,
KF
