Manufacturer: New Japan Radio

Overview: DUAL STEPPER MOTOR DRIVER NJM3772 s GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key Features

  • Dual chopper driver.
  • 1000mA continuous output current per channel.
  • Specially matched to the Dual DAC NJU39610.
  • Packages DIP22 / PLCC28 s BLOCK.
