Motor Drivers, Controllers datasheet and documents for TMC2226-SA-T

TMC2226-SA-T

Motor Drivers, Controllers Overview

The TMC2226-SA-T is a silent stepper motor driver IC designed for two-phase bipolar stepper motors. It supports input voltages from 4.75V to 29V DC and delivers up to 2.8A peak coil current with 2A RMS capability. The device features StealthChop2 for noiseless operation, SpreadCycle for high-dynamic control, and CoolStep for energy savings of up to 75%. It offers microstep resolution via pin settings (8, 16, 32, or 64) and achieves smooth 256-microstep running through MicroPlyer interpolation. Configuration is managed via a single-wire UART interface and OTP memory.

Motor Drivers, Controllers Feature Summary

StealthChop2 technology ensures ultra-silent motor operation suitable for indoor environments
CoolStep automatic current control optimizes energy efficiency by adapting to load conditions
StallGuard4 enables sensorless load and stall detection for homing applications
Integrated pulse generator allows standalone motion control without continuous CPU intervention
