TECHNICAL DATA

TRIAC PHASE ANGLE CONTROLLER

KKA1185A

The KKA1185A generates controlled triac triggering pulses and allows tachless speed stabilization of universal motors

by an integrated positive feedback function. Typical applications are power hand tools, vacuum cleaners, mixers, light

dimmer and other small appliances.

• Supply Power Obtained from AC Line

• Can be used with 220 V/50 Hz or 110 V/60 Hz

• Low Count/Cost External Components

• Optimum Triac Firing (2nd and 3rd Quadrants)

• Repetitive Trigger Pulses when Triac Current is

Interrupted

by Motor Brush Bounce

• Triac Current Sensing to Allow Inductive Loads

• Programmable Soft-Start
