The TMC2209 is an integrated circuit designed for extremely quiet operation of two-phase stepper motors. Its circuitry is compatible with older drivers and the TMC2208.
TRINAMIC's innovative StealthChop2 chopper ensures smooth and noiseless motor movement with maximum efficiency and excellent torque. Thanks to the fast current control and the possibility to combine it with SpreadCycle technology, it enables dynamic movements with high precision. The StallGuard function enables sensorless guidance. The protection and diagnostic functions of the integrated MOSFET power transistors provide robust and reliable operation up to a maximum motor current of 2 A RMS.
An easy-to-use UART interface opens up customization and control options, allowing fine tuning for optimal performance.
This industry-leading STEP/DIR stepper driver model delivers advanced designs that ensure noiseless and precise operation.
Specifications include the TMC2209 driver chip, dimensions of 15.24 x 20.32 mm, supply voltage of 4.75 - 28 VDC, maximum peak current of 2.8 A, maximum effective current of 2 A, IO supply of 3 - 5 V, RSense value of 100MΩ, RDSon value of 0.2Ω, maximum resolution of 256, standby current reduction function, and support for operating modes such as UART, STEP/DIR, stealthChop, spreadCycle, coolStep, and stallGuard.
