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 • Power Failure Detection and General Circuit Reset • Low Power Consumption; 6.
