Description
The NJM3775 is a switch-mode (chopper), constant-
current 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
Features
- Dual chopper driver.
- 750 mA continuous output current per channel.
- Digital filter on chip eliminates external filtering components.
