A3983SLPT DMOS MICROSTEPPER MOTOR DRIVER IC

A3983SLPT DMOS MICROSTEPPER MOTOR DRIVER IC

The A3983SLPT is a complete micro stepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A3983 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes. The translator is the key to the easy implementation of the A3983. Simply inputting one pulse on the STEP input drives the motor one micro step. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. The A3983 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
