POWER DRIVER FOR STEPPER MOTORS

INTEGRATED CIRCUITS

TMC262 DATASHEET

Universal, cost-effective stepper driver for two-phase bipolar motors with state-of-the-art features.

External MOSFETs fit different motor sizes. With Step/Dir Interface and SPI.

APPLICATIONS

Textile, Sewing Machines

Factory Automation

Lab Automation

Liquid Handling

Medical

Office Automation

Printer and Scanner

CCTV, Security

ATM, Cash recycler

POS

Pumps and Valves

Heliostat Controller

CNC Machines

FEATURES AND BENEFITS

High Current up to 8A Motor current using external (N&P)

MOSFETs.

DESCRIPTION

The TMC262 driver for two-phase stepper

motors offers an industry-leading feature

set, including high-resolution micro-

stepping, sensorless mechanical load

Highest Voltage up to 60V DC operating voltage

Highest Resolution up to 256 microsteps per full step

Smallest Size 5x5mm QFN32 package

measurement,

load-adaptive

power

Low Power Dissipation synchronous rectification

EMI-optimized slope & current controlled gate drivers

optimization, and low-resonance chopper

operation. Standard SPI™ and STEP/DIR

interfaces simplify communication. The

TMC262 drives four external N- and P-

channel dual MOSFETs for motor currents

up to 8A and up to 60V. Integrated

protection and diagnostic features support

robust and reliable operation.

Protection & Diagnostics overcurrent, short to GND,

overtemperature & undervoltage

stallGuard2™ high precision sensorless motor load detection

coolStep™ load dependent current control for energy savings

up to 75%

High integration, high energy efficiency

and small form factor enable miniaturized

designs with low external component

count for cost-effective and highly

competitive solutions.
