A4988 Driver Introduction: A4988 is a complete micro stepper motor driver with built in converter for easy operation. It can run bipolar stepper motors in full, half, 1/4, 1/8 and 1/16 step modes with output drive capability up to 35 V and ± 2 A. The A4988 includes a fixed off time current regulator, which is in slow or mixed decay mode. The A4988 converter is the key to easy implementation. The "stepper" input drives the motor one microstep forward with a single pulse input. There are no phase sequencing tables, high frequency control lines or complex programming interfaces. The A4988 interface is ideal for situations where complex microprocessors are unavailable or overburdened. A4988 Driver Features And Advantages: Low RDS (On) Output Automatic Current Decay Mode Detection or Selection Mixed With Slow Current Decay Mode Synchronous Rectification For Low Power Consumption Internal Under Voltage Lockout Cross Current Protection 3.3 And 5 V Compatible Logic Supplies Thermal Shut Down Circuitry Ground Fault Protection Load Short Circuit Protection Five Selectable Stepping Modes: Full Step, 1/2, 1/4, 1/8, and 1/16
