The A3983SLPTR-T from Allegro Microsystems is a complete microstepping motor driver designed for bipolar stepper motors. It operates in full, half, quarter, and eighth step modes, offering an output drive capacity of up to 35 V and ±2 A. The integrated translator simplifies implementation, requiring only a STEP input pulse for each microstep, making it suitable for applications without complex microprocessors.
This driver features automatic current decay mode selection, supporting both Slow and Mixed decay modes. It includes synchronous rectification for reduced power dissipation and internal protection circuitry such as thermal shutdown, undervoltage lockout (UVLO), and crossover-current protection. The device is supplied in a 24-pin TSSOP package with an exposed thermal pad, suitable for surface mounting.
Key electrical specifications include an operating voltage range of 8V to 35V and an output current rating of 2A. The operating temperature range is -20°C to 150°C (TJ). The A3983SLPTR-T is designed for general-purpose applications requiring precise motor control.
