Functional Diagram

Description

The MLX90804 is a power control IC for controlling

the speed of AC motors by means of a triac. The

speed setting is done by applying a ratiometric

voltage at pin SET (usually by means of

VDD

Gate

sensing

potentiometer). This speed setting is compared with

the pulse rate at the SPD input. The input is

compatible with inductive and magnetic detectors.

The calculation of the required phase angle is done

with a PI regulator, which is fully digital.

A soft start function is implemented to eliminate high

current peaks at startup. Also available are an

overload and overspeed protection.
