TECHNI CAL DATA
TRIAC PHASE ANGLE CONTROLLER
ILA1185A
The ILA1185A 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

This pin is the negative supply for the chip and clamped at -8.6 V by an internal zener.
This pin supplies - 1.0V triac trigger pulse at twice the line frequency.
Not connected.
The value of the capacitor at this pin determines the slope of the ramp.
Not connected.
This pin senses if the triac is on, and if so, will disable the gate trigger pulse.
The internal timing of the chip is set by the frequency of the voltage at this pin
This pin is the output of the feedback and the variation in voltage is averaged out by the
capacitor.
The change in load current is detected by the change in voltage across R9.
The bias current for the circuit is determined by the resistor value at this pin.
Not connected.
The voltage at this pin sets the no-toad firing angle.
The firing angle is slowly increased from 180o to the set value of Pin 12.
