The converter is the key to the easy implementation of the\u00a0A4988.<\/p>\n<p>There are no phase sequence tables, high-frequency control interface programming, etc. The application of the A4988\u00a0interface is very suitable for a complex microprocessor is not available or overloaded. In the stepping operation, the chopping control in the\u00a0A4988\u00a0automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increase step accuracy, and reduce power consumption.<\/p>\n<p>Provide internal synchronous rectification control circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.<\/p>\n<p>Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO), and crossover current protection.
