LV8121V-TLM-H

The LV8121V-TLM-H is a 3-phase brushless Motor Driver uses a PWM drive technique. The motor speed is controlled by changing the PWM duty that based on an analogue voltage input. This motor driver includes an automatic return constraint protection circuit and is optimal for driving fan motors.

• PWM control based on an analogue 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 and low-voltage shutdown protection circuit
• Thermal shutdown protection circuit
• 1.7W Allowable power dissipation
