FEATURES
Suitable for driving single-phase brushless DC motors, PWM speed control cooling fans, etc. block, integrated H-bridge output power tube. Highly integrated digital speed regulation, analog It has speed regulation, undervoltage protection and over-temperature protection functions. It is more convenient to install and use. application ÿ Single-phase brushless DC motor ÿ Single-coil brushless DC fan ÿ CPU cooling fan ÿWide operating voltage range (3.5~16V), PWM can be used Speed regulation, MINSP analog signal speed regulation, or DC voltage regulation Fast. ÿ PWM speed regulation: can be achieved by adjusting the duty cycle of the PWM signal Speed regulation. Wide input frequency range (100Hzÿ100KHz). ÿ With soft start function, it can eliminate the peak current generated during startup. ÿ The minimum speed output can be set as needed. ÿ The PWM end has an internal pull-up resistor. ÿ Soft switching function design reduces fan commutation noise. ÿ Complete protection functions:...
