Nuvoton KA44180A Stepper Motor Driver

KA44370A 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.

 

Stepper motors are used in office automation, industrial equipment, and required to have low heat generation, low vibration, and low EMI. Nuvoton stepper motor drivers can control bipolar two phase stepper motors with a single chip.

 

Mixed-decay automatic control which is one of our strengths in current control technology, helps to constantly detects and attenuates excessive current that does not contribute to torque. This function help to easily realize low heat generation and low vibration drive. In addition, the original power drive control suppresses noise, when a large output current is needed, contributing to low EMI of the motor.
