NJM3777 - DUAL STEPPER MOTOR DRIVER

General Description

s PACKAGE OUTLINE The NJM3777 is a switch-mode (chopper), constant-current driver with two channels: one for each winding of a two-phase stepper motor.

The NJM3777 is equipped with a Disable input to simplify half-stepping operation.

Key Features

  • Dual chopper driver.
  • 900 mA continuous output current per channel.
  • Digital filter on chip eliminates external filtering components.
  • Package EMP24(Batwing) s BLOCK.

NJM3777 DUAL STEPPER MOTOR DRIVER s GENERAL DESCRIPTION s PACKAGE OUTLINE The NJM3777 is a switch-mode (chopper), constant-current driver with two channels: one for each winding of a two-phase stepper motor. The NJM3777 is equipped with a Disable input to simplify half-stepping operation. The NJM3777 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 NJM3777E3 diodes. Voltage supply requirements are + 5 V for logic and + 10 to + 45 V for the motor. Maximum output current is 900mA per channel.
