STEPPER MOTOR CONTROLLER
NJU7380
s GENERAL DESCRIPTION
NJU7380 is a controller with transrator which convert
from input step and direction pulse to driver's phase signal
for full and half step.
NJU7380 translates from pulse input signal (Serial
interface) to phase signal input, so NJM3700 series dual
channel bipolar drivers or NJM2672 dual H-bridge driver
can be easily controlled by a micro processor .
NJU7380 is also including Auto Current Down (ACD)
circuit which is suitable for reducing power dissipation of
power devices and motor.
