The A4988 driver Stepper Motor Driver is a complete micro-stepping motor driver with built-in converter and is 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).
\nA4988 driver Stepper Motor Driver includes a fixed off-time current regulator, the regulator can be in slow or mixed decay mode. The converter is the key to the easy implementation of the A4988.
\nInternal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection. 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.
