SLOSE70 December 2020 DRV8434S
The peak current in a stepper driver is limited by the overcurrent protection trip threshold IOCP. The peak current describes any transient duration current pulse, for example when charging capacitance, when the overall duty cycle is very low. In general the minimum value of IOCP specifies the peak current rating of the stepper motor driver. For the DRV8434S, the peak current rating is 4 A per bridge.
