We have a prototype board with the STSPIN958 full bridge but we see that it cannot measure positive current (in coil) when the voltage is switched negative, output shows current = 0.
We switch from 48V to -48V on the coil. (turning the magnetic field off fast)
When the current becomes also negative then we have a measurement again.
So we have a blind spot after the voltage polarity on our output changes.
Is there a configuration with this IC to keep measuring the current after the voltage polarity switches?
Thanks
