Overview

Voltage Range 2V (1.8V) to 11V DC
Battery Operation 1-2 Li-Ion cells, or min. 2 AA / NiMh cells
1 / 2 DC motors up to 2A / 2.4A with velocity & torque control
Direct Bridge control for solenoids, relays, lamps, motors
Standby <50nA typ. current draw

Single Wire UART for two-motor torque and velocity control
Low RDSon LS 170mΩ & HS 170mΩ (typ.)
Parallel Option for single DC motor
Motor Load Feedback available
Full Protection & Diagnostics
Tiny of QFN 3*3 with 20 pins

Working from a single or dual Li-Ion cell or dual or more AA batteries the TMC7300 is optimally suited for battery operated equipment. Its two full-bridges allow either control of two DC motors, PWM-control of LEDs, or protected standalone peripheral driving, using a polarity signal per halfbridge. Operate up to two DC motors via simple UART control for direction, velocity and torque. Integrated power-MOSFETs with internal charge-pump for best-in-class RDSon even at low supply voltage, handle motor current up to 1.2A per motor continuously, or the double current in parallel connection. Together with a tiny standby current, this guarantees a long battery life. Protection and diagnostic features support robust and reliable operation. This advanced driver ensures efficient and reliable operation for cost-effective and highly competitive solutions.

Product Details

The TMC7300-EVAL allows you to explore all functions of the TMC7300-LA DC motor driver IC.

The TMC7300-EVAL-KIT is a set of one MCU board Landungsbruecke, a Eselsbruecke bridge board and one TMC7300-EVAL driver board. It allows for a quick and simple start within only minutes to make your motor turning, while still providing full access to all registers and full functionality and diagnostics.

For diagnosis, all signals between MCU and TMC7300 are accessible with probes on the bridge board. TMC7300-EVAL can be used with or without the Landungsbruecke MCU board. .

All you need to get started is a power supply and ADI Trinamic's free and easy to use TMCL-IDE. This graphical user interface allows quick setup and supports the use of commands in direct mode, monitors real-time behavior visualized in graphs, and logs and stores data. All settings can simply be exported for your own firmware project.
