The MLX90805 is a power control IC ideally suited for control of any resistive or inductive load regulated by a triac.

The MLX90805 was designed primarily for starting and speed control of AC motors, but will work equally well with any Inductive or resistive load such as Incandescent lights.

The MLX90805's primary purpose is to provide a "soft start" for a motor, preventing current inrush. The triac is controlled by a linear "ramp" from minimum to maximum power. Start rate can be varied from 0.5 sec. to 3 sec, by changing the option bits.

The secondary function of the MLX90805 is proper ignition of the triac for inductive and resistive loads, while keeping the triac's current consumption to a minimum.

Added features of MLX90805 include a frequency locked loop for stable ignition point.
