Analog Devices TMC5240

The TMC5240 is a smart high-performance stepper motor controller and driver IC with serial communication interfaces (SPI, UART) and extensive diagnostic capabilities. It combines a flexible, jerk-optimized ramp generator for automatic target positioning with industries’ most advanced stepper motor driver based on the 256 microsteps, built-in indexer and fully integrated 36V, 3.0AMAX H-Bridges plus non-dissipative integrated current sensing (ICS). The complete solution reduces the learning curve to a minimum while giving best-in-class performance.

GENERAL DESCRIPTION

ADI-Trinamic's sophisticated 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. The H-Bridge field-effect transistors (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 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). Since this current is limited by thermal considerations, the actual maximum RMS current depends on the thermal characteristics of the application (PCB ground planes, heatsinks, ventilation, etc). The maximum full-scale current per H-Bridge is IFS = 3.0A and can be set by an external resistor connected to IREF.
