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
