TMC248 DATASHEET (Rev. 1.01 / 2013-MAR-26)
2
APPLICATION EXAMPLES: HIGH POWER – SMALL SIZE
The TMC248 scores with its high power density and a versatility that covers a wide spectrum of
applications and motor sizes, all while keeping costs down.
APPLICATION EXAMPLES
COMPACT DESIGN FOR UP TO 3 MOTORS USING SPI INTERFACE
OFFLOAD THE MOTION CONTROL FUNCTION TO TRINAMICS TMC429. GET A COMPETITIVE DESIGN FOR MULTIPLE MOTORS!
By offloading the motion-control function to the TMC429, up to three motors can be operated reliably with very little
demand for service from the microcontroller.

MINIATURIZED DESIGN WITH SIMPLE DIGITAL DRIVER CONTROL
BENEFIT FROM A LARGE CURRENT CONTROL RANGE VIA ANALOG INPUTS!
The TMC248 is controlled via SPI bus. The microcontroller initializes the chip and writes control parameters, mode
bits, and values for coil currents in the driver chip. Analog A/B inputs allow for a large current control range.

MINIATURIZED DESIGN FOR STANDALONE MODE
REPLACE BIPOLAR DRIVER BY A MODERN CMOS DRIVER. USE NEW HARDWARE AND KEEP YOUR SOFTWARE INVEST!
The TMC248 is controlled by analog current control signals and digital phase signals. Especially for lower speeds
inimitable smoothness will be achieved with TRINAMICs low noise chopper.

EVALUATION & DEVELOPMENT PLATFORM
This evaluation board is a development platform for
applications based on the TMC248. The board features USB
interface for communication with control software running
on a PC. External power MOSFETs support drive currents up
to 3.5A at 24 V. The control software provides a user-
friendly GUI for setting control parameters and visualizing
the dynamic response of the motor.
