Dual Stepper Motor Driver

  • Dual chopper driver
  • 750mA continuous output current per channel
  • Digital filter on chip eliminates external filtering components
  • Packages (DIP22-D2/PLCC28-M2/SOP24 JEDEC 300mil(batwing))
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.
