MOTOROLA ANALOG IC DEVICE DATA
Triac Phase Angle Controller
The TDA1185A 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: 6.0 mA
