Características
Description:
A4988 is a complete microstepping motor driver with built-in translator for easy operation. The product can be full, half, 1/4, 1/8 and 1/16 step mode to operate bipolar stepper motor output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator can slow or mixed decay mode. The converter is the key to the easy implementation of the A4988. In inputting one pulse on the STEP input drives the motor one microstep. No phase sequence tables, high frequency control lines, or complex interfaces to programming. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened.
Specification:
- Low RDS (ON) outputs
- Automatic current decay mode detection / selection.
- Mixed with slow current decay modes.
- Synchronous rectification for low power dissipation.
- Internal UVLO.
- Crossover-current protection.
- 3.3 and 5 V compatible logic supply.
- Thermal shutdown circuitry.
- Ground Fault Circuit.
- Load short-circuit protection.
- Of five optional step mode: full, 1/2, 1/4, 1/8 and 1/16.
