Limiter−Power Supply — Allows operation of the CA3059 directly from an AC line. Suggested dropping resistor (RS) values are given in the table below. 2. Differential On/Off Sensing Amplifier — Tests for condition of external sensors or input command signals. Proportional control capability or hysteresis may be implemented using this block. 3. Zero−Crossing Detector — Synchronizes the output pulses to the zero voltage point of the AC cycle. This synchronization eliminates RFI when used with resistive loads. 4. Triac Drive — Supplies high−current pulses to the external power controlling thyristor. 5. Protection Circuit — A built−in circuit may be actuated, if the sensor opens or shorts, to remove the drive current from the external triac. 6. Inhibit Capability — Thyristor firing may be inhibited by the action of an internal diode gate at Pin 1. 7. High Power DC Comparator Operation — Operation in this mode is accomplished by connecting Pin 7 to Pin 12 (thus overriding the action of the zero−crossing detector). When Pin 13 is positive with respect to Pin 9, current to the thyristor is continuous. © Semiconductor Components Industries, LLC, 2006 1 July, 2006 − Rev. 2 Publication Order Number: CA3059/D CA3059 MAXIMUM RATINGS DC Supply Voltage (Between Pins 2 and 7) DC Supply Voltage (Between Pins 2 and 8) Peak Supply Current (Pins 5 and 7) Fail−Safe Input Current (Pin 14) Output Pulse Current (Pin 4) (Note 1) Junction Temperature Operating Temperature Range Storage Temperature Range Rating Symbol VCC VCC I5,7 I14 Iout TJ TA Tstg Value 12 12 ± 50 2.0 150 150 − 40 to + 85 − 65 to + 150 Unit Vdc Vdc mA mA mA °C °C °C ELECTRICAL CHARACTERISTICS (Operation @ 120 Vrms, 50−60 Hz, TA = 25°C [Note 2]) Characteristic Figure Symbol Min Typ Max Unit DC Supply Voltage Inhibit Mode RS = 10 k, IL =.
