Manufacturer: New Japan Radio

Overview: DUAL STEPPER MOTOR DRIVER NJM3773 s GENERAL.

Download the NJM3773D2 datasheet PDF. This datasheet also includes the NJM3773 variant, as both parts are published together in a single manufacturer document.

General Description

The NJM3773 is a switch-mode (chopper), constant-current driver with two channels: one for each winding of a two-phase stepper motor.

The NJM3773 is also equipped with a Disable input to simplify half-stepping operation.

The circuit is well suited for microstepping applications together with an external micro controller.

Key Features

  • Dual chopper driver.
  • 750 mA continuous output current per channel.
  • High impedance current control inputs.
  • Digital filter on chip eliminates external filtering components.
  • Packages DIP22 / PLCC28 / EMP24(Batwing) s BLOCK.
