TRINAMIC’s TMC2202-WA provides an integrated motor driver solution for 3D-printing, cameras, scanners, and other automated equipment applications. The stepper driver IC is a high-performance stepper motor driver IC with improved optical inspection capabilities. It uses a wettable flank QFN package to allow automatic optical inspection of the soldering joints.

The TMC2202-WA can drive motors with up to 1.2 A_RMS. Like all TRINAMIC stepper motor drivers, the component offers a step resolution of up to 256 microsteps per full step to achieve perfect sinusoidal control, even in systems with a limited achievable step pulse rate. Further development of TRINAMIC’s StealthChop2™ technology has all but eliminated motor noise at low speeds, making the precise control of stepper motors not only possible but also affordable for applications in environments that demand absolute silence, e.g., office buildings and residential areas. The device is designed for a supply voltage of 5 V to 36 V and has a step/direction input for fully autonomous operation, while the easy to use UART interface allows for more tuning and control options. Once the ideal settings are found, these can be stored in OTP memory.
