TMC2225-SA

Chip highlights:

Ultra-quiet, low-resonance stepper motor driver chip (internal drive, power MOS); can directly replace DRV8825 with PTP

Profile description

The TMC2225 is a two-phase stepper motor that implements an ultra-quiet, low-resonance driver chip. This chip pin is compatible with the DRV8825 legacy driver chip. The featured StealthChop2 function ensures ultra-quiet operation of the motor at low speeds; the SpreadCycle function suppresses high-speed resonance, greatly reduces motor jitter, and achieves smooth, high-speed operation. The internally integrated power MOSFET handles motor currents up to 1.4A RMS (peak 2A). Protection and diagnostics support safe, reliable operation of the chip. Drives ultra-quiet or low-jitter operation with a single pulse direction，The UART can also be used to configure the internal registers of the TMC2225 for a comprehensive and flexible operation of the motor.
