LV8121V Description
ENA2135 LV8121V Bi-CMOS IC For Fan Motor 3-phase Brushless Motor Driver http://onsemi. 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.
LV8121V Key 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
