Introduction
A3977SEDT Power Management IC DMOS Stepping Motor Driver 5V 44-Pin PLCC Tube
The A3977 is a complete microstepping motor driver, with builtin translator. It is designed to operate bipolar stepper motors in full, half, quarter, and eighth-step modes, with output drive capability of 35 V and ±2.5 A. The A3977 includes a fixed off time current regulator that has the ability to operate in slow, fast, or mixed decay modes. This current decay control scheme results in reduced audible motor noise, increased step accuracy, and reduced power dissipationThe translator is the key to the easy implementation of the A3977. Simply inputting one pulse on the STEP input drives the motor one step (two logic inputs determine if it is a full, half, quarter, or eighth step). There are no phase-sequence tables, high frequency control lines, or complex interfaces to program. The A3977 interface is an ideal fit for applications where a complex microprocessor is unavailable or over-burdened
