MC3479P

Overview

The MC3479P is a bipolar stepper motor driver manufactured by onsemi, designed for driving two-phase bipolar stepper motors. It operates on a single power supply ranging from 7.2V to 16.5V and delivers a per-coil drive current of 350mA with a maximum output current of 0.5A. The device features TTL/CMOS compatible inputs with a minimum input hysteresis voltage of 400mV. It supports clockwise and counter-clockwise rotation control along with full-step and half-step operation modes. The component is housed in a 16-pin DIP-16 through-hole package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

Supports full-step and half-step operation modes with selectable high or low output impedance in half-step mode
Integrates built-in clamp diodes to suppress back electromotive force (back EMF)
Features phase logic initialization to Phase A with open-collector status indication

Applications

Two-phase bipolar stepper motor control systems
Industrial automation equipment requiring precise rotational positioning
Embedded motion control applications utilizing TTL/CMOS logic interfaces

Procurement Notes

Verify the specific manufacturer part number against official documentation to confirm compatibility with existing designs. Note that product lifecycle status may affect long-term availability; consult current datasheets for active production status and recommended replacement components if necessary.

Selection Notes

Select this component for applications requiring simple single-supply bipolar stepper motor control without complex external circuitry. Ensure the power supply voltage remains within the 7.2V to 16.5V range and that the load current does not exceed the specified 350mA per coil limit. Verify thermal management requirements for the DIP-16 package under continuous operation conditions.

Part Context

The MC3479P belongs to the family of bipolar stepper motor drivers produced by onsemi. It is engineered for straightforward integration into motor control circuits, offering built-in protection features such as back EMF suppression. The device simplifies design by combining logic decoding, sequencing, and drive stages in a single package, reducing the component count required for basic stepper motor applications.
