NJM13775 DUAL STEPPER MOTOR DRIVER „ GENERAL DESCRIPTION The NJM13775 is a switch-mode (chopper), constant current driver with two channels: one for each winding of a two-phase stepper motor. NJM13775 is equipped with a Disable input to simplify half-stepping operation. The NJM13775 contains a clock oscillator, 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 500mA per channel. NJM13775 achieved downsizing a motor control board by adopting small LQFP package, making this IC ideal for a multiple motor control board.
