A4988 Driver Introduction: A4988 is a complete micro stepper motor driver with built in converter, easy to operate. The bipolar stepper motor can operate in full step, half step, 1/4, 1/8, and 1/16 step modes, with an output drive capacity of up to 35V and ±2A. A4988 includes a fixed off time current regulator that is in slow or mixed decay mode. The A4988 converter is the key to easy implementation. The step input only requires one pulse to drive the motor forward one microstep. There is no phase sequence table, control line, or complex programming interface. The A4988 interface is very suitable for situations where complex microprocessors are unavailable or overloaded.
A4988 Driver Features and Advantages:
1. Low RDS (on) output
2. Automatic current decay mode detection or selection
3. Mixing with slow current decay mode
4. Synchronous rectification, low power consumption
5. Internal undervoltage locking
6. Constant current protection
7. 3.3 and
