Description
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
Typical applications
- Pump
- Fan for Consumer electronics / Fan for White goods
- Office equipment
