com Overview 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.
Added Functions • Supports origin shifting in the speed control function • Adds a dedicated pin for setting the soft start time This allows a longer start time to be set without reducing the response time when changing speed.
• FG output pin added Functions and 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 inpu...
