Monolithic Power Systems (MPS) MP6602 35V Stepper Motor Drivers

Monolithic Power Systems (MPS) MP6602 35V Stepper Motor Drivers include an integrated indexer/translator and internal current regulation. The MPS MP6602 doesn’t need external current-sense resistors. The devices operate from 4.5V to 35V input voltage (V_IN) and can provide up to 4A of motor current per phase, depending on temperature and PCB layout. The MP6602 supports full, half, quarter, eighth, 1/16, and 1/32-step modes for bipolar or unipolar stepper motors.
