LB11970RV  
Monolithic Digital IC  
For Fan Motor  
http://onsemi.com  
Single-phase Full-wave Driver  
Overview  
The LB11970RV is a motor driver of the single phase bipolar drive that a good direct PWM drive of the motor drive  
efficiency can come true easily. It is most suitable for the power supply fan of the personal computer, CPU air  
conditioner fan drive.  
Functions  
• Single-phase full-wave drive (16V to 1.2A output transistor incorporated)  
• Variable speed function using thermistor input and external signal incorporated  
→Enables silent and low-vibration variable speed control through direct PWM control with separately-excited upper  
Tr  
• Current limiter circuit (limit at I =480mA with R =1Ω connection, the limiter value determined with Rf)  
O
L
• Kick-back absorption circuit incorporated  
• Low-consumption, low-loss, and low-noise drive enabled by the soft switching circuit during phase shift  
• Regeneration Di incorporated with less external parts  
• HB incorporated  
• Lock protection and automatic reset functions incorporated  
• RD (Lock detection) output  
• Thermal shutdown circuit incorporated

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.  
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high  
current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.  
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating  
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
