Zero-Voltage Switches 50Hz-60Hz 400Hz Thyristor Control Applications
CA3059 CA3079 zero-voltage switches monolithic silicon integrated circuits designed control thyristor variety power switching applications input voltages 24V, 120V, 208/230V, 277V 50Hz-60Hz 400Hz. Each zero-voltage switches incorporates functional blocks (see Functional Block Diagram) follows: Limiter-Power Supply Permits operation directly from line. Differential On/Off Sensing Amplifier Tests condition external sensors command signals. Hysteresis proportional-control capability easily implemented this section. Zero-Crossing Detector Synchronizes output pulses circuit time when cycle zero voltage point; thereby eliminating radio-frequency interference (RFI) when used with resistive loads. Triac Gating Circuit Provides high-current pulses gate power controlling thyristor. addition, CA3059 provides following important auxiliary functions (see Functional Block Diagram). built-in protection circuit that actuated remove drive from triac sensor opens shorts. Thyristor firing inhibited through action internal diode gate connected Terminal High-power comparator operation provided overriding action zero-crossing detector.

CA3059, CA3079 Operating Considerations
Power Supply Considerations CA3059 CA3079 CA3059 CA3079 intended operation selfpowered circuits with power supplied from line through dropping resistor. internal supply designed allow some current drawn auxiliary power circuits. Typical power supply characteristics given Figures 2(b) 2(c). Power Supply Considerations CA3059 output current available from internal supply adequate higher power applications. such applications external power supply with higher voltage should used with resulting increase output level. (See Figure peak output current characteristics.) When external power supply used, Terminal should connected Terminal synchronizing voltage applied Terminal illustrated Figure 5(a). Operation Built-In Protection CA3059 special feature CA3059 inclusion protection circuit which, when connected, removes power from load sensor either shorts opens. protection circuit activated connecting Terminal Terminal shown Functional Block Diagram. assure proper operation protection circuit following conditions should observed: internal supply limit external load current with dropping resistor. value sensor resistance (RX) between 100k. ratio typically, should greater than 0.33 less than either these ratios with unmodified sensor over entire anticipated temperature range, then either series shunt resistor must added avoid undesired activation circuit. operation protection circuit desired under conditions other than those specified above, then apply data given Figure External Inhibit Function CA3059 priority inhibit command applied Terminal presence least +1.2V 10µA will remove drive from thyristor. This required level compatible with logic. logical activates inhibit function. Gate Current Mode CA3059 Connecting Terminals disables zero-crossing detector permits flow gate current demand from differential sensing amplifier. This mode operation useful when comparator operation desired when inductive loads switched. Care must exercised avoid overloading internal power supply when operating this mode. sensitive gate thyristor should used with resistor placed between Terminal gate order limit gate current.
Dimensions parentheses millimeters derived from basic inch dimensions indicated. Grid gradations mils (10-3 inch).
photographs dimensions represent chip when wafer. When wafer into chips, cleavage angles instead with respect face chip. Therefore, isolated chip actually mils (0.17mm) larger both dimensions.
