DRV8426E: DRV8426E/P max current IOCP and IREG

Hello,

I'm considering using the DRV8426P to drive 2 Brushed DC motors.
I have questions questions about current limitations IOCP and IREG.
In the datasheet, we can see find the following informations:
- IOCP is at least 2.5A.
- IREG is defined with the equation: IREG (A) = VREFx (V) / KV (V/A) = VREFx (V) / 1.32 (V/A). with   0.05V < VREF < 3.3v
  => IREG MAX= 3.3/2.2= 1.5A
 So, my question is: In wich case IOCP will be reached, considering that IREG will regulate the current to 1.5A?
 
 Best Regards

Sylvain
