ON MC3479P

驱动器 - 全集成，控制和功率级350mA7.2V ~ 16.5V

Overview

The MC3479 is designed to drive a two−phase stepper motor in the bipolar mode. The circuit consists of four input sections, a logic decoding/sequencing section, two driver−stages for the motor coils, and an output to indicate the Phase A drive state.

Features • Single Supply Operation: 7.2 to 16.5 V • 350 mA/Coil Drive Capability • Clamp Diodes Provided for Back−EMF Suppression • Selectable CW/CCW and Full/Half Step Operation • Selectable High/Low Output Impedance (Half Step Mode) • TTL/CMOS Compatible Inputs • Input Hysteresis: 400 mV Minimum • Phase Logic Can Be Initialized to Phase A • Phase A Output Drive State Indication (Open−Collector) • Pb−Free Package is Available*
