MP6602 - Next-Gen Dual Full-Bridge Motor Driver
Motor Driver with Stall Detection
Monolithic Power Systems (MPS) introduces the MP6602, a 35V stepper motor driver featuring integrated stall detection, a serial interface, a built-in indexer/translator, and internal current regulation that eliminates the need for external current-sense resistors. It operates from 4.5V to 35V, delivers up to 4A per phase, and supports both bipolar and unipolar stepper motors in full-step, half-step, quarter-step, eighth-step, 1/16-step, and 1/32-step modes.

- Rotor stall and open-load detection
- Over-current protection (OPC)
- Over-voltage (OVP) and under-voltage protection (UVP)
- Thermal warning and thermal shutdown
Advanced Control and Feedback
The automatic hold current mode can lower the winding current to automatically save power when a full current is not required, such as when the motor is stopped or lightly loaded.
The motor’s back EMF (BEMF) can be measured. The BEMF can be read via the serial interface for advanced diagnostic and control functions. The serial interface sets control modes such as the step mode, direction, and output current. The serial interface can also read diagnostic registers. The STEP and DIR input pins can adjust motor motion without serial bus transactions.
