DUAL STEPPER MOTOR DRIVER NJM3772

DUAL STEPPER MOTOR DRIVER NJM3772






n GENERAL DESCRIPTION n PACKAGE OUTLINE
The njm3772d2 is a stepper motor driver, which circuit is
especially developed for use in microstepping applications in
conjunction with the matching dual DAC (Digital-to-Analog
Converter) NJU39610.
The NJM3772 contains a clock oscillator, which is common
for both driver channels, a set of comparators and flip-flops
implementing the switching control, and two H-bridges with
internal recirculation diodes. Voltage supply requirements are
+5 V for logic and +10 to +45V for the motor. Maximum output
current is 1000mA per channel.
n FEATURES
• Dual chopper driver
• 1000mA continuous output current per channel
• Specially matched to the Dual DAC NJU39610
• Packages DIP22 / PLCC28
