Allegro MicroSystems A4989SLDTR-T Environmental and export classification status description
The A4989SLDTR-T is a complete microstepping motor driver with built-in translator for easy operation. It operates from a 3V to 5.5V supply voltage and can deliver up to 2A per coil. Its adjustable current control, mixed decay modes, and overcurrent and overtemperature protection make it an ideal choice for stepper motor applications. Functions: The A4989SLDTR-T integrates a fixed off-time PWM current control, automatic mixed decay mode, and an internal synchronous rectification control circuitry that provides optimized performance and switching noise. It also provides a full set of protection functions, including under-voltage lockout, over-current protection, and thermal shutdown. Applications: This IC is suitable for a wide range of microstepping applications, including printers, scanners, CNC machines, and other automated equipment where precise control of the motor is required. Alternative Parts: Alternative stepper motor driver ICs that can be used instead of the A4989SLDTR-T include the Allegro A4988, TI DRV8825, and STMicroelectronics L6470. Embedded Modules: The A4989SLDTR-T does not have embedded modules, but it can be easily integrated into motor control systems using microcontroller-based interfaces. Q&A: 1. Q: What is the maximum supply voltage for the A4989SLDTR-T? A: The A4989SLDTR-T operates from a 3V to 5.5V supply voltage. 2. Q: Can the A4989SLDTR-T deliver constant current to stepper motors? A: Yes, the A4989SLDTR-T features adjustable current control for providing constant current to the stepper motors. 3. Q: What kind of protection does the A4989SLDTR-T offer? A: The A4989SLDTR-T provides under-voltage lockout, overcurrent protection, and thermal shutdown for enhanced system reliability and safety. 4. Q: Can the A4989SLDTR-T be used in 3D printers? A: Yes, the A4989SLDTR-T is commonly used in 3D printers for precise control of stepper motor movements. 5. Q: What are the primary decay modes supported by the A4989SLDTR-T? A: The A4989SLDTR-T features automatic mixed decay mode, which optimizes performance and reduces switching noise in motor control applications.
