| ILA1185A TRIAC PHASE ANGLE CONTROLLER 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 Intenupted 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 Pin Connection VEE Gate trigger NC Ramp Generator NC Current Cense Voltage Cense 1 2 3 4 5 6 7 14 13 12 11 10 9 8 VCC Soft start Finning Angle Set NC Bias Current Feedback Input Integration Cap Figure 1.

Gate Trigger Pulse This pin supplies - 1.0V triac trigger pulse at twice the line frequency. NC Not connected. Ramp Generator The value of the capacitor at this pin determines the slope of the ramp. NC Not connected. Current Sense This pin senses if the triac is on, and if so, will disable the gate trigger pulse. Voltage Sense The internal timing of the chip is set by the frequency of the voltage at this pin Integration Capacitor This pin is the output of the feedback and the variation in voltage is averaged out by the capacitor. Feedback Input The change in load current is detected by the change in voltage across R9. Current Program The bias current for the circuit is determined by the resistor value at this pin. NC Not connected. Phase Angle Set The voltage at this pin sets the no-toad firing angle. Soft-Start The firing angle is slowly increased from 180o to the set value of Pin 12. VCC Ground 3 |
