NJM3775 - DUAL STEPPER MOTOR DRIVER

Description

The NJM3775 is a switch-mode (chopper), constantcurrent driver with two channels: one for each winding of a two-phase stepper motor.

NJM3775 is equipped with a Disable input to simplify half-stepping operation.

Features

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

NJM3775 DUAL STEPPER MOTOR DRIVER s GENERAL DESCRIPTION The NJM3775 is a switch-mode (chopper), constantcurrent driver with two channels: one for each winding of a two-phase stepper motor. NJM3775 is equipped with a Disable input to simplify half-stepping operation. The NJM3775 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, including recirculation diodes. Voltage supply requirements are + 5 V for logic and + 10 to + 45 V for the motor. Maximum output current is 750mA per channel.
