How to interface a motor controller say the MC33033 or equiv. to a motor driver say the TI DRV8881E or equiv?

Not according to the spec sheet I read!\

The DRV8881 is a bipolar stepper or brushed-DC
motor driver for industrial applications. The device
output stage consists of two N-channel power
MOSFET H-bridge drivers.

YES. Still it will control my 4 phase motor, 1 half H-bridge per phase. So, my question still remains how to interface it with MC33033

I don't think it will.
You do not have access to the driving logic directly so there is no way to get all the phase switching you will need for a BLDC, as far as I can see anyway.
What electronics and programming experience do you have?
Making BLDC controllers is not exactly straight forward.
And I think quite a bit more info is needed so can you expand your question so we know what you want to drive the motor with (micro, DCin, switches.... ?) as all that will help formulate an answer.
And the supply volts and motor power too please.

It will, this is confirmed by TI whose motor driver DRV8881E drives the motor. The motor controller used is MC33033 which interfaces with the DRV8881E to drive the motor. The problem which I have is interfacing the MC33033 to the DRV. Again, TI APP ENG says this is all that's req'd..
V=24VDC, I =1.5A

I am trying a DRV8881EEVM from TI but am having problems d'loading the app program; even TI could not help. Anyone care to try?
Thanks

I have given up on the TI 8881DRV, so want to connect the MC33033 directly to an H Bridge. Just not sure if there is an H Bridge that I can directly connect to the MC33033? Any help appreciated.
