The EV6602-V-01A is an evaluation board designed to demonstrate the capabilities of the MP6602, a stepper motor driver with a built-in indexer and internal current regulation. It is suitable for 3D printers, laser printers, copiers, and textile machines.

The MP6602 operates across a 4.5V to 35V input voltage (V_IN) range. It can deliver up to 4A of motor current per phase, and can operate a bipolar or unipolar stepper motor in full-, half-, quarter-, eighth-, 1/16- and 1/32-step modes.

The MP6602 offers automatic hold current mode, which can automatically lower the winding current to save power when the full current is not required (e.g. when the motor is stopped or under light-load conditions). In this mode, the motor step position is held.

Stall detection is achieved by measuring the motor’s back electromotive force (BEMF), and comparing it to a preset value.

Internal safety features and diagnostic functions include under-voltage lockout (UVLO) protection, over-voltage protection (OVP), over-current protection (OCP), open-load detection (OLD), stall detection, over-temperature warning (OTW), and over-temperature shutdown (OTS).

The MP6602 has excellent thermal performance, with a temperature rise of only about 26°C above the ambient temperature (while the evaluation board drives 4A of motor current). It is available in a small QFN-25 (4mmx5mm) package.
