NJM3774D2 - DUAL STEPPER MOTOR DRIVER

Download the NJM3774D2 datasheet PDF. This datasheet also covers the NJM3774 variant, as both devices belong to the same dual stepper motor driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The NJM3774 is a switch-mode (chopper), constantcurrent driver with two channels: one for each winding of a two-phase stepper motor.

The NJM3774 is equipped with a TTL level compatible Disable input to simplify half-stepping operation.

Key Features

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

NJM3774 DUAL STEPPER MOTOR DRIVER s GENERAL DESCRIPTION The NJM3774 is a switch-mode (chopper), constantcurrent driver with two channels: one for each winding of a two-phase stepper motor. The NJM3774 is equipped with a TTL level compatible Disable input to simplify half-stepping operation. The circuit is well suited for microstepping applications together with the matching dual DAC NJU39610. In full/half stepping applications, the NJM3517 can be used as a phase generator (translator) to derive the necessary signals for the NJM3774. The NJM3774 contains a clock oscillator, which is common for both driver channels, a set of comparators and flip-flops implementing the switching control, and two output H-bridges. Voltage supply requirements are +5 V for logic and +10 to +45 V for the motor.
