Model Number: A4988 Brand Name: New and Original Key Specifications/Special Features: Description:A4988 is a complete microstepping motor driver with built-in translator for easy operationThis product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 AA4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modesA4988 converter is the key to the easy implementation
  • As long as the "step" input inputting one pulse drives the motor one microstep
  • There are no phase sequence tables, high frequency control lines, or complex interfaces to program
  • A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened
  • In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (slow or mixed)
  • In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime
  • Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption
  • Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption
  • Internal circuit protection includes: thermal shutdown with hysteresis, under-voltage lockout (UVLO), and crossover-current protection
  • Special power sequencing
  • A4988 surface mount QFN package (ES), a size of 5 x5mm, nominal overall package height of 0.90mm, with an exposed pad for enhanced thermal dissipation
  • This package is Pb (suffix-T), with 100% matte tin lead frame plating
  • Features:
    • Simple step and direction control interface
    • Short-to-ground and shorted-load protection
    • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
    • Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
    • Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
  • Packingincluded:
    • 1 x step motor driver module
    • 1 x heatsink
