Features and Benefits

Power Stage for the TMC8670-EVAL
4 independent Half-Bridges with Gate Driver and Phase Current up to 2A RMS (TMC-UPS-2A24V-EVAL) / 10A RMS (TMC-UPS-10A70V-EVAL) RMS for driving a 2-phase stepper motor, or a 3-phase BLDC or a single phase DC motor.
Main Supply Voltage (VM) up to 24V (TMC-UPS-2A24V-EVAL) / 70V (TMC-UPS-10A70V-EVAL)
Supply for Gatedrivers and Shunt Amplifiers (zero current level = 3.3V/2)
2 Phase Current shunt amplifiers and one for bottom shunt with +/-2A (TMC-UPS-2A24V-EVAL) / +/-10A (TMC-UPS-10A70V-EVAL) measurement range

Product Details

TMC-UPS-2A24V-(A)-EVAL / TMC-UPS-10A70V-(A)-EVAL is a universal Power Stage.

It drives up to 2A / 10A of current and is tolerant to supply voltages up to 24V / 70V. It uses half bridge gate drivers and discrete MOSFETs as well as standard connectors for supply and motor connection. Current measurement is implemented by inline shunt amplifiers.

The Power Stages TMC-UPS-2A24V-A-EVAL and TMC-UPS-10A70V-A-EVAL (5V supply for shunt amplifiers) are optimized for usage with TMC4671-EVAL.
