Product Summary

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 NJM3772D2 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 of the NJM3772D2 are +5 V for logic and +10 to +45V for the motor. Maximum output current is 1000mA per channel.
