The TMC5262 is a compact, high-power, single axis stepper motor controller and driver designed for highly integrated, energy efficient motion systems. It supports a wide 4.5V to 65V supply range and integrates low-impedance power MOSFETs to enable high efficiency and low heat generation.
The TMC5262 integrates advanced motion control, intelligent diagnostics, adaptive current regulation, and high-power motor driving into a single compact device.
Beyond the advanced on-chip diagnostics, additional capabilities include motor coil resistance measurement, passive braking and freewheeling modes, on-chip temperature and supply monitoring, comprehensive fault protection, and a real-time on chip scope interface (RT OCSI) for in system tuning and validation.
All functionality is packaged in a compact, thermally optimized 30-lead, 6mm × 6mm FCQFN, making the IC well suited for space constrained medical pump designs. Together, these features allow motors to operate at extremely low current when unloaded while dynamically supplying torque only when needed, minimizing heat and maximizing efficiency.
