            TMC5272 Dual-Axis Stepper Motor Controller and Driver IC
                    Analog Devices' TMC5272 is a 2.1 V to 20 V, 2 × 0.8 Arms two-axis stepper driver and eight-point motion controller
    

Image of Analog Devices' TMC5272 Dual-Axis Stepper Motor Controller and Driver IC ADI's TMC5272 is a miniaturized, smart, high-performance dual-axis stepper motor controller and driver IC with serial communication interfaces (SPI and UART) and extensive diagnostic capabilities. High integration, high energy efficiency, and a small form factor enable miniaturized and scalable systems for cost-effective solutions.

StealthChop2™ ensures noiseless operation combined with maximum efficiency and optimal motor torque control.

The TMC5272 combines two flexible 8-point ramp generators with reduced jerk for automatic positioning with two smart stepper motor drivers based on a 256-microstep built-in indexer and four fully integrated 20 V, 1.1 A_MAX H-bridges plus non-dissipative integrated current sensing (ICS), which eliminates bulky external sense resistors resulting in space and power savings.

The integrated power MOSFETs' low impedance results in high driving efficiency and minimal heat generation. The typical total R_DS(ON) (high side plus low side) is 0.31 Ω with a maximum RMS current per H-bridge of I_RMS = 0.8 A_RMS and a maximum output current per H-Bridge at I_MAX = 1.5 A_MAX (limited by overcurrent protection).

The TMC5272 features abundant diagnostics and protection functions such as short-circuit protection/overcurrent protection, thermal shutdown, and undervoltage lockout.

The TMC5272-EVAL allows evaluation of the TMC5272 in combination with the ADI TRINAMIC evaluation board system or as a stand-alone board. It uses the standard schematic and offers several options to test different modes of operation.
