Dual Stepper Motor Driver

Features
  • Dual chopper driver
  • 650mA output current per channel
  • Selectable slow/fast current decay for improved highspeedmicrostepping
  • Specially matched to Dual DAC NJU39610
  • Packages (DIP22-D2/SOP24 JEDEC 300 mil(Batwing)/PLCC28-M2)
General Description
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.
