STEPPER MOTOR DRIVER
NJM2673
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
The NJM2673 is a stepper motor driver, which consists of a
LS-TTL compartible logic input stage, off time control circuits
and a pair of highpower H-bridges and protection diodes.
The output current is up to 1000mA.
The NJM2673 with small number of external components
conforms a complete control and drive unit for stepper motor
systems.
