Vref for current setting running 24 Volts

I will run my DRV8825 with 24 Volts…
Is there an difference in the Vref compared running with 12 Volts ?

E.G With 12 Volts I set Vref to 0,5 Volt so I get 1A current (= Vref *2)

is this the same running 24 Volts ? or will the formula change somehow ?

Thanks in Advance


Hello, Gerhard.

The current limiting circuit uses the DRV8825 chip’s internal 3.3V regulator, so it should be the same when using 12V or 24V.
