Product Summary
The NJM3775FM2 is a switch-mode (chopper), constantcurrent driver with two channels: one for each winding of a two-phase stepper motor. NJM3775FM2 is equipped with a Disable input to simplify half-stepping operation. The NJM3775FM2 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.Each channel of the NJM3775FM2 consists of the following sections: an output H-bridge with four transistors and four recirculation diodes, capable of driving up to 750 mA continuous current to the motor winding, a logic section that controls the output transistors, an S-R flip-flop, and a com- parator. The clock-oscillator is common to both channels.
