The 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. Highest integration, high energy efficiency, and a small form factor enable miniaturized and scalable systems for cost-effective solutions.
StealthChop2™ ensures absolutely noiseless operation combined with maximum efficiency and the 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 20V, 1.1AMAX 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 RDS(ON) (high side plus low side) is 0.31Ω with a maximum RMS current per H-bridge of IRMS = 0.8ARMS and a maximum output current per H-Bridge at IMAX = 1.5AMAX (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 is available in a tiny 2.97mm × 3.13mm, 36-pin WLCSP package.
