Stepper Motor Drive Circuit

FEATURES

DESCRIPTION

•

Half-step and Full-step Capability

The UC3717 has been designed to control and drive the current in

one winding of a bipolar stepper motor. The circuit consists of an LS-

TTL-compatible logic input, a current sensor, a monostable and an

output stage with built-in protection diodes. Two UC3717s and a few

external components form a complete control and drive unit for LS-

TTL or micro-processor controlled stepper motor systems.

Bipolar Constant Current Motor Drive

Built-in Fast Recovery Schottky

Commutating Diodes

•

Wide Range of Current Control 5-1000mA

Wide Voltage Range 10-45V

The UC1717 is characterized for operation over the full military tem-

perature range of -55°C to +125°C, the UC2717 is characterized for

-25°C to +85°C, and the UC3717 is characterized for 0°C to +70°C.

Designed for Unregulated Motor Supply
