POWER DRIVER FOR STEPPER MOTORS

INTEGRATED CIRCUITS

TMC248 DATASHEET

Low-cost stepper driver for two-phase bipolar motors with low noise PWM chopper and stallGuard™.

External MOSFETs fit different motor sizes. With SPI, classic analog interface, protection & diagnostics.

APPLICATIONS

Textile, Sewing Machines

Office Automation

Printer and Scanner

Heliostat Controller

ATM, Cash recycler

POS

CCTV, Security

Antenna Positioning

Pumps and Valves

Lab Automation

Liquid Handling

Medical

FEATURES AND BENEFITS

High Current up to 7 A motor current using 4 external dual-

MOS transistors.

DESCRIPTION

The TMC248 driver for two-phase stepper

motors offers a competitive feature set,

including 64x micro-stepping, sensorless

Voltage Range 7 V… 36 V DC

3.3 V or 5 V DC for digital part

mechanical load measurement with stall

detection, and smart current control.

Standard SPI™ and communication via

external analog / digital signals are

available. The TMC248 drives eight external

Low-RDS-ON high efficiency MOSFETs for

motor currents up to 7A and up to 36V.

Integrated protection and diagnostic

features support robust and reliable

operation. High integration and small form

factor enable miniaturized designs with

low external component count for cost-

effective and highly competitive solutions.

SPI & External Analogue / Digital Signals

Microstep Resolution up to 64 microsteps per full step

Low Power Dissipation via low RDS-ON power stage

Protection: overvoltage, overtemperature & short circuit

Diagnostics: overcurrent, open load, overtemperature,

temperature prewarning, and undervoltage

stallGuard™ sensorless stall detection and load measurement

Mixed Decay for smooth motor operation

Slope Control for reduced electromagnetic emissions

Current Control for cool motor and driver

Standby and Shutdown Mode

Smallest Size 5x5mm QFN28 package
