Bi-CMOS IC  
For Fan Motor  
LV8121V  
3-phase Brushless Motor Driver  
Overview  
The LV8121V is a three-phase brushless motor driver that uses a PWM drive technique. The motor speed is controlled  
by changing the PWM duty that based on an analog voltage input. This motor driver includes an automatic return  
constraint protection circuit and is optimal for driving fan motors.  
Features  
• PWM control based on an analog voltage input (the CTL voltage), synchronous rectification  
• One Hall-effect sensor FG output  
• Automatic return constraint protection circuit (ON/OFF=1/15)  
• Start/Stop switching circuit, Forward/Reverse switching circuit  
• Current limiter circuit, Low-voltage shutdown protection circuit, Thermal shutdown protection circuit

Caution 1) Absolute maximum ratings represent the values 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.
