TMC5222AWV+T

TMC5222AWV+T is a miniaturised single-axis stepper motor controller and driver with an I2C interface, in a 30-ball wafer-level chip-scale package of 2.3 mm by 2.49 mm, for battery-operated and space-constrained designs such as wearables, optical lens drives, surveillance cameras, liquid handling and small printers. It drives stepper motors from 2.1 V to 16 V at up to 1.4 A RMS coil current (2 A sine peak) with 256 microsteps per full step, lossless integrated current sensing, StealthChop2 for noiseless motion, SpreadCycle for dynamic moves, and sensorless StallGuard load detection with CoolStep adaptation that can cut energy use by up to 75 percent. The integrated eight-point motion controller generates minimum-jerk ramps autonomously, the STEP/DIR interface with MicroPlyer interpolation remains available for simple hosts, and TriCoder provides sensorless standstill step-loss detection. Logic levels of 1.1 V to 2 V match mobile processors, and diagnostics cover overcurrent, short circuits, supply voltage and temperature. Selection advice: choose the TMC5222 when an I2C bus is the control path already present in your design; pick the TMC5221 instead when the host offers SPI.
