NJM3776D2 - DUAL CONTROLLER FOR HIGH-CURRENT STEPPER MOTOR

Download the NJM3776D2 datasheet PDF. This datasheet also covers the NJM3776 variant, as both devices belong to the same dual controller for high-current stepper motor family and are provided as variant models within a single manufacturer datasheet.

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.

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.

NJM3776 DUAL CONTROLLER FOR HIGH-CURRENT STEPPER MOTOR s 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. The NJM3776 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 sections each containing four outputs, two source and two sink, intended to drive an external Hbridge. Voltage supply requirements are +5 V for logic and +10 to +45 V for the outputs.
