DRV8805 Freewheeling

$

0

Hello team , 

the excitation of the coils in the above schematic is at 5V 

where as the Vclamp is at 24V 

This is done by my customer in accordance to the 

Where it says VSS needs to be greater than VMM, 

Now i am unable to understand how will the Inductor current freewheel , if it has been changed by a 5V supply and then later it goes on to freewheel in a 24V supply ( vclamp) 

are we doing something wrong here ?

Actually the issue is , there are two supplies which can be connected to the excitation coils , 

5V or 24V, 

What would you recommend me to connect to Vclamp

Vcaml = excitation voltage respectively 

or Vclamp = 24V always 

Thank you so much for your help
