NJM3775 Datasheet | New Japan Radio

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 mon for both driver channels, a set of parators 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. s PACKAGE OUTLINE NJM3775D2 NJM3775E3 NJM3775FM2 s Features - Dual chopper driver - 750...
