KA44180A is a two channel H-bridge driver that controls bipolar stepping motor with a single chip. The interface is a parallel control and it is possible to drive two phase excitation, half-step, 1-2 phase excitation, and W1-2 phase excitation methods. PWM drive contributes to high-speed, low-vibration drive with OFF time control and Mixed-decay control. The input voltage is compatible with 12V / 24V system, making it ideal for home appliances, office automation equipment and factory automation equipment.
