Analog Devices Inc./Maxim Integrated TMC2590-TA

Overview

TMC2590-TA from TRINAMIC Motion Control GmbH & Co. KG is a high-voltage, high-current stepper motor driver IC designed to control external N- and P-channel MOSFETs for two-phase bipolar stepper motors. It delivers 1–8 A motor current at 5–60 V DC supply, supports up to 256 microsteps per full step via MicroPlyer™ interpolation, and integrates SpreadCycle™ chopper, StallGuard2™ load sensing, and CoolStep™ adaptive current control - enabling precision motion in compact industrial motion systems.

For engineers reviewing the TMC2590-TA datasheet, TMC2590-TA pinout, TMC2590-TA application, or TMC2590-TA equivalent, key selection criteria include its external MOSFET architecture, SPI/STEP-DIR dual interface support, differential current sensing capability, integrated protection (short-to-GND/VS, overtemperature, undervoltage), and compatibility with the TMC26x family for migration paths.

Technical Context

The TMC2590-TA operates as an intelligent gate driver controller-not a power stage-using internal DACs, sine/cosine tables, and real-time chopper logic to generate precise coil current waveforms. Its SpreadCycle™ algorithm replaces traditional constant-off-time chopping with adaptive hysteresis and slope control to minimize torque ripple and EMI, while StallGuard2™ extracts back-EMF from sense resistor signals to deliver sensorless load measurement without added components.

It features dual-mode operation: full SPI-configurable mode for advanced diagnostics and real-time parameter tuning, and stand-alone mode using three configuration pins (CSN/SCK/SDI) to set current scale (CS=15 or 31), chopper hysteresis (HSTRT=2 or 6), and microstep resolution (256 native or 16×16 interpolated). The internal 15 MHz oscillator and clock selector allow flexible timing without external crystals.

FAQ

What is the maximum motor current supported by the TMC2590-TA?

The TMC2590-TA supports motor currents from 1 A to approximately 8 A RMS, determined by external MOSFET selection, sense resistor value, and current scale setting (CS=15 or CS=31). Peak current capability depends on thermal design and MOSFET SOA - the IC itself does not limit current; it controls gate drive timing and protection thresholds. For sustained 8 A operation, use low-R_DS(on) N+P MOSFET pairs and ensure adequate PCB copper and heatsinking for the TMC2590-TA's exposed pad.

Does the TMC2590-TA require external gate drivers for 60 V operation?

No, the TMC2590-TA does not require external gate drivers for 60 V operation when using complementary N- and P-channel MOSFETs. Its integrated high-side drivers reference VHS (VS − 10 V), eliminating bootstrapping or charge-pump circuits. However, for voltages above 60 V or currents beyond 8 A, TRINAMIC recommends adding external gate drivers like the MAX5064B - though this configuration forfeits short-to-VS protection and requires careful BBM timing alignment.

How does StallGuard2™ work on the TMC2590-TA without current sensors?

StallGuard2™ on the TMC2590-TA measures motor load by analyzing back-EMF voltage induced in the unenergized coil during each chopper cycle - derived from the differential sense resistor signals (SRA/SRBL and SRB/SRAL). It requires no additional sensors or wiring; the IC computes a 10-bit load value correlated to mechanical torque and rotor angle. This enables stall detection, sensorless homing, and CoolStep™ current adaptation - all using only the standard two-sense-resistor interface.

Can the TMC2590-TA operate without an SPI interface?

Yes, the TMC2590-TA supports full stand-alone operation using three configuration pins (CSN, SCK, SDI) to set microstep resolution (256 native or 16× interpolated), chopper hysteresis (HSTRT=2 or 6), and current scale (CS=15 or 31). In this mode, it defaults to SpreadCycle™, resonance dampening, 136°C overtemperature detection, and StallGuard2™ with fixed SGT=2 - enabling immediate motion control with only STEP/DIR signals and external MOSFETs, no firmware or SPI host required.

What package type and thermal considerations apply to the TMC2590-TA?

The TMC2590-TA uses a thermally enhanced TQFP-32 package (7 mm × 7 mm body, 5 mm × 5 mm exposed die pad) with GND-connected thermal pad. To maintain safe junction temperatures below 150°C, the PCB must provide ≥300 mm² of 2-oz copper connected to the pad via ≥6 thermal vias (0.3 mm diameter, filled or plated). TRINAMIC specifies 470 nF ceramic capacitance on 5VOUT and 220 nF on VHS - both placed within 2 mm of their respective pins - to stabilize gate drive and prevent oscillation under high di/dt loads.
