LB8502M
Overview
The LB8502M easily and simply implements feedback-based motor speed control in combination with a general-purpose
motor driver IC.
Compared to open-loop control, the use of speed feedback allows the motor speed precision to be improved and the speed
fluctuations due to load variations to be minimized.
LB8502M: For use as a driver IC that increases the motor speed as the command voltage rises (three-phase systems)
Features
Achieves linear speed control
Applications can set the slope of the change in motor speed with change in the input duty.
Minimized speed fluctuations in the presence of line or load variations
Allows a minimum speed to be set
Soft start function
Settings using external capacitors and resistors (to support easier mass production of end products)
Supports both PWM duty and analog voltage control inputs
