NJM3772 DUAL STEPPER MOTOR DRIVER s GENERAL DESCRIPTION The NJM3772 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 NJM3772 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 are +5 V for logic and +10 to +45V for the motor.
Maximum output current is 1000mA per channel.
