NJM3776D2 Datasheet Dual Controller For High-current Stepper Motor

Manufacturer: New Japan Radio

Overview: NJM3776 DUAL CONTROLLER FOR HIGH-CURRENT STEPPER MOTOR s GENERAL.

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

General Description

The NJM3776 is a switch-mode (chopper), constant-current controller intended for controlling external transistors in a high current stepper motor application.

The NJM3776 has two channels, one for each winding of a two-phase stepper motor.

The NJM3776 is equipped with a Disable input to simplify half stepping operation.

Key Features

  • Suitable to drive any external MOS FET or bipolar power transistor.
  • Cross conduction prevented by time delay.
  • Digital filter on chip eliminates external filtering components.
  • Package DIP24 s BLOCK.
