Overview

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.
