-The A4988 driving force Stepper Motor Driver is a entire micro-stepping motor motive force with built-in converter, smooth to function.
-It operates from 8 V to 35 V and can deliver up to about 1 A in line with section without a warmth sink or pressured air flow (it is rated for 2 A per coil with sufficient additional cooling).
-A4988 motive force Stepper Motor Driver consists of a set off-time cutting-edge regulator, the regulator can be in sluggish or blended decay mode.
-The converter is the important thing to the easy implementation of the A4988.
-There are no phase sequence tables, the high-frequency control interface programming etc.
-The application of A4988 interface is very suitable for a complex microprocessor is not available or overload.
-In the stepping operation, the chopping control in the A4988 automatically selects the current decay mode (slow or mixed). The mix decay current control scheme can reduce the audible motor noise, increased step accuracy, and reduced power consumption.
-Provide internal synchronous rectification control circuitry, in order to improve the pulse width modulation (PWM) power consumption during operation.
-Internal circuit protection includes thermal shutdown with hysteresis, under-voltage lockout (UVLO) and crossover current protection.
-Don’t need special power-up sequencing. 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.
Features :
-Automatic current decay mode detection/choice.
-Mixed with slow current decay mode.
-The low power dissipation of synchronous rectifier.
-Internal UVLO(ultra voltage lockout).
-Crossover current protection.
-Thermal shutdown circuit.
-Ground fault protection.
-Loading and short circuit protection.
-The optional five-step mode: full, 1/2, 1/4, 1/8 and 1/16.
