Stand Alone Stepper Motor Driver with Step/Direction (2,1A/36V)
The TMC2210 is a high-performance stepper motor driver IC with configuration options through package pins and additional diagnostic outputs. It combines industries’ most advanced stepper motor driver based on the 256 microsteps built-in indexer and two fully integrated 36V, 3.0A (max) H-Bridges plus non-dissipative integrated current sensing (ICS).
ADI-Trinamic's StealthChop2 chopper ensures absolutely noiseless operation combined with maximum efficiency and best motor torque.
High integration, high energy efficiency, and a small form factor enable miniaturized and scalable systems for costeffective solutions while giving best in class performance. The H-Bridge FETs have very low impedance resulting in high driving efficiency and minimal heat generated. The typical total R ON (high side + low side) is 0.23 Ω. The maximum output current per H-Bridge is I MAX = 5.0 A limited by the Overcurrent Protection (OCP).
The maximum RMS current per H-Bridge is I RMS = 2.1 A at room temperature assuming a 4-layers PCB.
The maximum full-scale current per H-Bridge is IFS = 3.0 A and can be set by an external resistor connected to IREF.
This current is defined as the maximum current setting of the embedded current drive regulation circuit. The nondissipative ICS eliminates the bulky external power resistors resulting in a dramatic space and power saving compared with mainstream applications based on external sense resistor.
The TMC2210 features diagnostics and protections such as short protection/OCP, thermal shutdown, undervoltage lockout (UVLO).
During thermal shutdown and UVLO events, the driver is disabled.
