LV8121VSLDGEVK: 3.5A, 3-Ph BLDC Hall, 8 ~ 35V

Summary

The LV8121VGEVK evaluation kit is designed to quickly assess the LV8121 part, a three-phase brushless motor driver that uses a PWM drive technique. The motor speed is controlled by changing the PWM duty, which is 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
