NJM3774 DUAL STEPPER MOTOR DRIVER s GENERAL DESCRIPTION The NJM3774 is a switch-mode (chopper), constantcurrent driver with two channels: one for each winding of a two-phase stepper motor. The NJM3774 is equipped with a TTL level patible Disable input to simplify half-stepping operation. The circuit is well suited for microstepping applications together with the matching dual DAC NJU39610. In full/half stepping applications, the NJM3517 can be used as a phase generator (translator) to derive the necessary signals for the NJM3774. The NJM3774 contains a clock oscillator, which is mon for both driver channels, a set of parators and flip-flops implementing the switching control,...
