Monolithic Digital IC  
For Fan Motor  
LB11970FV  
Single-phase Full-wave Driver  
Overview  
The LB11970FV is a single-phase full-wave driver for fan motor.  
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 =1connection, 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  
FG (rotation detection) output  
Thermal shutdown circuit incorporated
