The NJM3777 is a switch-mode (chopper)constant-current driver with two channels: one for each winding of a two-phase stepper motor. The NJM3777 is equipped with a Disable input to simplify half-stepping operation. The NJM3777 contains a Clock oscillatorwhich is common for both driver channelsa set of Comparators and Flip-Flops implementing the switching controland two output H-bridgesincluding recirculation Diodes Voltage supply requirements are + 5 V for Logic and +10 to +45 V for the motor. Maximum output current is 900mA per channel.
