■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJM3771 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 NJM3771 contains a clock oscillator, which is
common for both driver channels; a set of comparators and
flip-flops imple menting the switching control; and two
H-bridges with internal recirculation diodes. Voltage supply
requirements are +5 V for logic and +10 to +45 V for the
motor. Maximum output current is 650 mA per channel.
■ FEATURES
● Dual chopper driver
● 650mA output current per channel
● Selectable slow / fast current decay for improved highspeed
microstepping
● Specially matched to Dual DAC NJU39610
● Packages DIP22-D2 / PLCC28-M2
