We have an application to power a stepper motor driver with TPS2663 efuse. We have enabled reverse polarity protection as well as reverse current blocking. While doing the tests it seems like we are getting some faults from the driver when the efuse with RPP and RCB are used (at high speeds or 10 rps and while changing direction). When we use the efuse without the RPP and RCB the faults do not occur. When we add a regen clamp between the between the efuse output and the motor driver input, we don't see the faults anymore. We belive that this might be due to some back emf. Do you have any experience with this issue?
These are the conditions where we are seeing the faults:
Current limit: 6A
Supply Voltage to driver: 48 V or 24 V
Motor Speed: 10 rps
Nominal Phase Current of the motor: 5.5 A
Rated voltage of the motor: 3.56 V
