For StepStick and Pololu A4988 compatible hardware. Drive capability up to 1.7A continuous coil current, up to 2.8A peak. Step/Dir interface with microstep interpolation (up to 256 microsteps). Configurable via CFG pins or UART interface. StealthChop2 for quiet operation and smooth motion. Extended high dynamic motor control chopper available through UART, OTP, or CFG pins. CoolStep current control for energy savings. StallGuard4 sensorless motor load detection. TMC2209 is an ultra-quiet motor driver IC for two-phase stepper motors. Pin compatible with many traditional drivers and TMC2208. Advanced StealthChop2 technology ensures noise-free operation, high efficiency, and consistent motor torque. Fast current regulation and resonance suppression enable high dynamic performance. StallGuard allows homing without sensors and prevents stalling. Built-in power MOSFET handles motor currents up to 2A, with protection and diagnostic features for stable and reliable operation. Easy-to-use UART interface enables tuning and control options. Application settings can be stored in OTP memory. Drive can be configured for silent and precise operation via pulse direction interface, providing a cost-effective and competitive solution.
