ADuM3221 to drive a brushed motor

I would like to use a ADuM3221A to drive a brushed DC motor.
Input voltage levels are 5V. Idea is to directly connect the DC motor with a  limiting 12 R resistor to the output pins VoA and VoB.

VDD2 is 8V, motor  current around 0.8A.

Depending on the input levels, it should be possible to  drive the motor bidirectional.

 

Will it be possible or any concernds?

 

A TC4426 and opto-coupler were used in a former design
