EVALUATION BOARD

TMC-UPS-2A24V-A-EVAL Evaluation Board

Hardware Version V1.00 | Document Revision V1.00 • 2019-APR-15

The TMC-UPS-2A24V-A-EVAL is a universal Power Stage for usage with TMC4671-Eval. It drives up

to 2A of current and is tolerant to supply voltages up to 24V. It uses half bridge gate drivers and

discrete MOSFETs as well as standard connectors for supply and motor connection. Current mea-

surement is implemented by inline shunt ampliﬁers.

Features

•

Power Stage for the TMC4671-EVAL

•

4 independent Half-Bridges with Gate

Driver and Phase Current up to 2A

RMS for driving a 2-phase stepper

motor, or a 3-phase BLDC or a sin-

gle phase DC motor.

•

Main Supply Voltage (VM) up to 24V

•

Supply for Gatedrivers and Shunt

Ampliﬁers (zero current level = 5.0V/2)

•

2 Phase Current shunt ampliﬁers

and one for bottom shunt with +/-

2A measurement range

It is based on the TMC-UPS-2A24V-EVAL V1.10. Please assemble all components properly according to guidelines in the respective Motion Controller Evaluation Board Manual. 2 Hardware Information All design ﬁles for our evaluation boards are available for free.

This part is only needed on an Evaluation board for user convenience. 3 Usage with own Motion Controller The TMC-UPS-2A24V-A-EVAL can be used with third party motor controller. In that case 5V needs to be supplied via the Motor Controller connector. SPI signals are not needed.

The default setting is R34 = 5V, which results in a zero current offset of 5.0V/2 = 2.5V as required by TMC4671-EVAL. When using the TMC4670-EVAL or TMC8670-EVAL, R33 should be placed (0R) and R34 should not be equipped to change the zero current offset to 3.3V/2 = 1.66V.
