A3982SLBTR-T IC MTR DRV BIPOLAR 3-5.5V 24SOIC Bipolar Motor Driver DMOS Logic 24-SOIC

Product Details

A3982SLBTR-T Description

The A3982SLBTR-T is a complete stepper motor driver with a built-in translator for easy operation. It is designed to operate bipolar stepper motors in full- and half-step modes, with an output drive capacity of up to 35 V and ±2 A. The A3982SLBTR-T includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes. Simply inputting one pulse on the STEP input drives the motor one step. There are no phase sequence tables, high-frequency control lines, or complex interfaces to program. The A3982SLBTR-T interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
