Green A4988 driver Stepper Motor Driver- Normal Quality

The Green A4988 driver Stepper Motor Driver- Normal Quality

A complete micro-stepping motor driver with built-in converter, easy to operate.

• Operating Voltage: 8V to 35V
• Phase Current: Up to 1A per phase (2A per coil with cooling)
• Current Regulator: Fixed off-time
• Decay Mode: Slow or mixed decay
• Control Interface: No phase sequence tables or high-frequency programming
• Features:
  • Automatic current decay mode detection
  • Internal UVLO and thermal shutdown
  • Improved PWM power consumption
  • Surface mount QFN package

The A4988 driver Stepper Motor Driver includes a fixed off-time current regulator and can operate in slow or mixed decay mode. It is suitable for applications where a complex microprocessor is not available or overloaded. The chopping control automatically selects the current decay mode, reducing motor noise and increasing step accuracy.

Internal circuit protection features thermal shutdown, under-voltage lockout, and crossover current protection. The driver does not require special power-up sequencing. It comes in a compact surface mount package with an exposed thermal pad for heat dissipation.

Attention: Connecting or disconnecting the motor while the driver is powered can damage the system.

Features:

• Automatic current decay mode detection/choice
• Mixed with slow current decay mode
• Internal UVLO (ultra voltage lockout)
• Crossover current protection
• Thermal shutdown circuit
• Ground fault protection
• Loading and short circuit protection
• Optional five-step mode: full, 1/2, 1/4, 1/8, and 1/16

Package Includes:

• 1 x Green A4988 driver Stepper Motor Driver- Standard Quality
• 1 x Heat sink
