The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with a built-in converter, easy to operate. It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).

A4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988.

There are no phase sequence tables, high-frequency control interface programming, etc. The application of the A4988 interface is very suitable for a complex microprocessor that is not available or overloaded. In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increase step accuracy, and reduce power consumption.

Provide internal synchronous rectification control circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.

Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. Don’t need special power-up sequencing. A4988 uses a surface mount QFN package (ES), the size is 5 mm × 5 mm, nominal overall package height is 0.90 mm, with an exposed thermal pad to enhance the heat dissipation function.

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

Note : HR4988 on chip working remains same.

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.
