For Fan Motor  
LB1975  
3-phase Brushless Motor Driver  
Overview  
The LB1975 is a 3-phase brushless motor driver IC suited for use in direct PWM driving of DC fan motors for air  
conditioners, water heaters, and other similar equipment. Since a shunt regulator circuit is built in, single power supply  
operation sharing the same power supply for the motor is supported.  
Features  
Withstand voltage 46V, output current 2.5A  
Direct PWM drive output  
3 built-in output top-side diodes  
Built-in current limiter  
Built-in FG output circuit
