JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD. Three-Phase Sine-wave Sensor-Less Fan Motor Driver CJDR5958 1 Motor Driver Introduction CJDR5958 is a three-phase brush-less DC motor drive integrated circuit. It provides a sensor-less speed control scheme and adopts a sine wave signal drive mode, which can better reduce the noise generated during the operation of the motor drive circuit. CJDR5958 internally integrates the starting circuit, back EMF commutation control, pulse width modulation (PWM) speed control, lock protection and thermal shutdown circuit. Therefore, CJDR5958 is very suitable for applications where low motor driving noise is required, such as game machines and CPU cooling devices. 3 Features • • • PWM Quasi-Sinusoidal Driver Three-Phase Sensor-Less Drive Method Adjustable Forced Commutation Frequency (for Start-up) Built-In External PWM Speed Control Built-In Quick Start Function FG (Rotation Speed Detection) Output Soft Switching Circuit (for Noise Reducing) Power Saving Function (PWM Duty Input is 0%) Built-In Lock Protection and Auto Restart Function Thermal Shutdown Protection 4 Applications • • • Small Power Fan Water Pump CPU Water Cooling Pump • • • • • • • 2 Available Package PART NUMBER PACKAGE CJDR5958 DFNWB3×3-10L Note: For more detailed packaging information, see the part Pin Configuration and Function and the part Mechanical Information.
