The Green A4988 Stepper Motor Driver, classified as Normal Quality, offers a comprehensive solution for micro-stepping motor control, featuring a built-in converter for simplified operation. It operates efficiently within a voltage range of 8 V to 35 V and can deliver up to approximately 1 A per phase without the need for a heat sink or forced air flow, with a rated capacity of 2 A per coil achievable with adequate additional cooling.

Equipped with a fixed off-time current regulator, the A4988 driver supports both slow and mixed decay modes. Its integrated converter streamlines implementation, eliminating the need for complex phase sequence tables or high-frequency control interface programming. This makes it particularly suitable for use with complex microprocessors that may be unavailable or overloaded.

During stepping operations, the A4988 employs chopping control to automatically select the current decay mode, optimizing performance for reduced audible motor noise, enhanced step accuracy, and minimized power consumption.

The driver features internal synchronous rectification control circuitry to improve pulse width modulation (PWM) power consumption during operation, enhancing efficiency.

Internal circuit protection mechanisms, including thermal shutdown with hysteresis, under-voltage lockout (UVLO), and crossover current protection, ensure reliable performance without the need for special power-up sequencing.

Packaged in a compact surface mount QFN package (ES) measuring 5 mm × 5 mm, with a nominal overall package height of 0.90 mm, the A4988 includes an exposed thermal pad to enhance heat dissipation capabilities, contributing to its efficient operation.

Attention! The connection and disconnection of the motor, while the driver is turned on, can damage the system.

Note: The difference between product “A4988 driver Stepper Motor Driver- Standard Quality” and “A4988 driver Stepper Motor Driver- Good Quality” is, The good quality A4988 has more number of PCB layers and it features the connecting pins which are of gold plated as compared to other.

Features :

  1. Automatic current decay mode detection/choice.
  2. Mixed with slow current decay mode.
  3. The low power dissipation of synchronous rectifier.
  4. Internal UVLO(ultra voltage lockout).
  5. Crossover current protection.
  6. Thermal shutdown circuit.
  7. Ground fault protection.
  8. Loading and short circuit protection.
  9. The optional five-step mode: full, 1/2, 1/4, 1/8 and 1/16.
