• Manufacturer Part Number: MLX90805
• Description: Intelligent Triac Controller
• Manufacturer: ETC [List of Unclassifed Manufacturers]

Soft Start Only
The chip is used to perform smooth soft start of an
electrical motor. It detects when the mains voltage is
applied and generates firing pulses for the triac. The
motor starts running, and the maximum speed (motor
operating at full power) is reached after a predefined
time. This application is defined by fixing V(SET) =
Vref. This means, after soft start generation, always
the maximum speed (corresponding to the highest
ROM address) is selected.
