  • The LB8503V is an improved functionality version of the LB8500 and LB8502 products that features the added functions listed below. The LB8503V supports both single-phase and three-phase applications.
  • Features
  • Achieves linear speed control
  • 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
  • [Added Function] : Supports origin shifting in the control function
  • [Added Function] : Adds a dedicated pin for setting the soft time.
    This allows a longer start time to be set without reducing the response time when changeing speed.
  • [Added Function] : FG output pin added
