Analog Devices TMC5241
The TMC5241 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 the industry’s most advanced stepper motor driver based on the 256 microsteps, built-in indexer and fully integrated 65V, 3.0AMAX H-bridges, plus non-dissipative integrated current sensing (ICS). The complete solution reduces the learning curve to a minimum while giving best-inclass 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 cost-effective 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 0.31Ω. The maximum RMS current per H-bridge is IRMS = 2ARMS with VS = 24V and IRMS = 1.7ARMS with VS = 48V supply at room temperature, assuming a four-layer PCB. Since this is a thermal limit, the actual maximum RMS current depends on the thermal characteristics of the application (PCB ground planes, heatsink, ventilation). The maximum full-scale current per H-bridge is IFS = 3.0AMAX 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.
