Hello,
We are using the NJM2673 stepper motor driver to drive stepper motors from a 36V rail.
The NJM2673 , as well as having internal H-Bridges, it has a 5V logic supply.
NJM2673 DATASHEET:
**broken link removed**
Sometimes the stepper motors are not used and yet still the NJM2673 is connected to the 36V rail.
-during these times when the stepper motors are idle, we switch off the 5V rail supply to the NJM2673 stepper driver IC’s..
(-this is so that the NJM2673 does not keep drawing current from the 5V rail when the stepper motors are not required to be used).
-my question is, ….
- do we risk damaging the NJM26763 by having the 36V rail connected to it when its 5V input pin has 0V on it?
