Overview
The TMC2240 is a smart high-performance stepper motor driver IC with serial communication interfaces (SPI, UART) and extensive diagnosis capabilities. It combines industries’ most advanced stepper motor driver based on the 256-usteps built-in indexer and two fully integrated 36V, 3.0AMAX H-Bridges plus non-dissipative Integrated Current Sensing (ICS). TRINAMIC's stealthChop2TM 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 cost effective 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 Ron (high side + low side) is 0.23Ω. The maximum output current per H-Bridge is 1MAX = 5.0AMAX limited by the Overcurrent Protection (OCP). The maximum RMS current per H-Bridge is IRMS = 2.1ARMS at room temperature assuming a 4-layers PCB. The maximum full-scale current per H-Bridge is 1FS = 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. TMC2240 features abundant diagnostics and protections such as short protection / OCP, thermal shutdown, under voltage lockout. During thermal shutdown and under voltage lockout events the driver is disabled. Furthermore, TMC2240 provides functions to measure the driver temperature, estimate the motor temperature, and measure one external analog input. The TMC2240 is available in a small TQFN32 5x5mm package and a thermally optimized TSSOP38 9.7×4.4mm with exposed pad.
