LB8503V: DC Fan Motor Speed Controller
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
