Description
NJM3771 DUAL STEPPER MOTOR DRIVER * GENERAL .
The NJM3771 is a stepper motor driver, which circuit is
especially developed for use in microstepping applications in conjunction with the matching du.
Features
* Dual chopper driver
* 650mA output current per channel
* Selectable slow / fast current decay for improved high-
speed microstepping
* Specially matched to Dual DAC NJU39610
* Packages
DIP22-D2 / PLCC28-M2
SOP24 JEDEC 300 mil (Batwing)
NJM3771FM2 ( PLCC28 )
* BLOC
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
