ADITMC2100-LA-T
Overview
The TMC2100-LA-T is a standalone bipolar stepper motor driver IC featuring integrated power MOSFETs capable of delivering up to 1.2A RMS output current. It operates from a wide supply voltage range of 5.5V to 46V and utilizes a simple Step/Dir interface for ease of integration with standard microcontrollers. The driver is specifically designed for high-precision, low-noise applications through advanced chopper technologies.
Why Choose This Part
The primary advantage is the StealthChop chopper, which enables noiseless motor operation at low to medium speeds. It also features SpreadCycle for high-speed dynamics and MicroPlyer, which allows 256-microstep resolution even when the controller provides lower resolution step pulses. Integrated protection features like short-circuit detection and thermal shutdown enhance system reliability without external components.
Applications
Key Specifications
Getting Started
To evaluate the driver, engineers can use the TMC2100-EVAL-KIT which provides a complete hardware platform for testing motor performance. Hardware configuration is simplified through logic pins for mode selection (CFG0-CFG5), allowing standalone operation without SPI firmware. Ensure adequate thermal sinking via the VFQFN exposed pad for operation at maximum current levels.
