I'm designing a PCB using a DRV8801PWP.
However, I'm a bit unsure if I need to add freewheeling diodes myself or not. In the typical applications, they don't show them, but I didn't found either an explicit mention that I don't need them.
Some information that might be relevant :
- supply voltage : 12.6V max
- motor current : about 1A max (stalling)
- motor's load has rather low inertia (some motors are used in rough torque control (ie nearly immobile), and the others for the wheels of the robot (low speed, high reduction ratio)
So do I need to add free-wheeling diodes?
