FEATURES AND BENEFITS Motor Current
from 1A to 8A using external (N&P) MOSFETs
D ESCRIPTION High Voltage
Range from 5V up to 60V DC operating voltage The TMC2590 driver for two-phase stepper
High Resolution
up to 256 microsteps per full step motors offers an industry-leading feature
Small Size
7x7mm TQFP32-EP package set, including high-resolution microstep- ping, sensorless mechanical load measure-
Low Power Dissipation
using MOSFET power stage ment, load-adaptive power optimization,
High Temperature Tolerance
due to low self-heating and low-resonance chopper operation.
EMI-optimized
slope & current controlled gate drivers Standard SPI™ and STEP/DIR interfaces simplify communication. The TMC2590 uses
Protection & Diagnostics
short to GND, short to VS / external N- and P-channel MOSFETs for overcurrent, programmable overtemperature & undervoltage motor currents from 1A up to roughly 8A.
StallGuard2™
high precision sensorless motor load detection No bootstrapping and charge-pump are re-
CoolStep™
load dependent current control saves up to 75% quired. Integrated protection and diag- nostic features support robust and reliable
MicroPlyer™
256 step smoothness with 1/16 step input. operation. High integration, high efficiency
SpreadCycle™
high-precision chopper for best current sine and small form factor enable miniaturized wave form and zero crossing designs with low external component
Differential Current Sensing
for quiet chopper operation count for cost-effective and highly competitive solutions. Interfacing is
Resonance Dampening
for mid-range velocity compatible to the TMC26x family.
