NJM3771 DUAL STEPPER MOTOR DRIVER
●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.
●FEATURES
■Dual chopper driver
■650mA output current per channel
■Selectable slow / fast current decay for improved highspeed microstepping
■Specially matched to Dual DAC NJU39610
