High-Power Stepper Gate Driver IC in Small, Robust Package

TRINAMIC TMC2590

The TMC2590 is Trinamic’s latest 2-phase stepper motor gate driver. Complete with protection and diagnostics, the EMI-optimized chip with low power dissipation enables miniaturized designs for highly competitive solutions.

TRINAMIC Motion Control announces the TMC2590, a 2-phase stepper motor gate driver with robust design and high power density. Covering a wide range of stepper motors with a 5 V…60 V DC operating voltage, it’s the cost-efficient solution for many applications including textile, factory and lab automation, 3D printing, liquid handling, medical, security, pumps and valves, and POS devices.

TRINAMIC - TMC2590

“Stepper gate driver ICs allow for powerful, flexible designs with a high current profile that perfectly matches the motor using external MOSFETs. Forming an on-chip solution, it greatly reduces design complexity and development time by reducing the application’s bill of materials and board space needed,” explains Michael Randt, Founder and CEO of TRINAMIC.

With a Step/Dir interface, SPI, and stand-alone operation, the TMC2590 can be used with industry-typical motion controllers generating step signals. To ensure microstepping regardless of the motion controller used, the TMC2590 features MicroPlyer™, Trinamic’s step pulse interpolator for advanced 1/256 microstepping using 1/16 step pules or lower.

Highly integrated and highly efficient, the TMC2590 offers industry-leading technologies including StallGuard2™ for sensorless homing and stall detection, CoolStep™ for load-dependent current control saving up to 75% energy, and SpreadCycle™ for highly dynamic positioning. A full set of diagnostics can be accessed via the interface while integrated protection can be tuned to work with different power stages and load conditions. These include short protection, open-load detection, temperature sensors, and undervoltage detection for improved system reliability.

Easy to implement, the driver comes with extensive support for fast design cycles and even shorter time-to-market. Both the TMC2590, the open-source TMC2590-EVAL, and the TMC2590-BOB are available from September.
