A4988 StepStick Stepper Motor Driver Module

RBD-0435

This breakout board for Allegro’s A4988 microstepping bipolar stepper motor driver features adjustable current limiting, overcurrent and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 V to 35 V and can deliver up to approximately 1A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient cooling).

Description

The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with 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).

There are no phase sequence tables, the high-frequency control interface programming etc. The application of A4988 interface is very suitable for a complex microprocessor is not available or overload. 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, increased step accuracy, and reduced 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 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.

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.

General Specification
Input Supply Voltage (VDC) 8 ~ 35
Operating Current (A) 1.0A(No Heatsink ), 2.0A (with Heat-Sinking)
