Analog Devices TMC2240

The TMC2240 is a smart high-performance stepper motor driver IC with serial communication interfaces (SPI, UART) and extensive diagnostic capabilities. It combines industries’ most advanced stepper motor driver based on the 256 microsteps, built-in indexer and two fully integrated 36V, 3.0AMAX H-Bridges plus non-dissipative integrated current sensing (ICS). The H-Bridge FETs have very low impedance resulting in high driving efficiency and minimal heat generated.

GENERAL DESCRIPTION

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 typical total RON (high side + low side) is 0.23Ω. The maximum RMS current per H-Bridge is IRMS = 2.1ARMS at room temperature assuming a four-layer PCB. The maximum output current per H-Bridge is IMAX = 5.0AMAX limited by the Overcurrent Protection (OCP). The maximum full-scale current per H-Bridge is IFS = 3.0A 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 TMC2240 features abundant diagnostics and protections such as short protection/OCP, thermal shutdown, undervoltage lockout (UVLO).
