APPLICATION INFORMATION
The CA3059 is a self–powered circuit, powered from the AC line through an appropriate dropping resistor (see Table A). The internal supply is designed to power the auxiliary power circuits. In applications where more output current from the internal supply is required, an external power supply of higher voltage should be used. To use an external power supply, connect Pin 5 and Pin 7 together and apply the synchronizing voltage to Pin 12 and the DC supply voltage to Pin 2 as shown in Figure 4. Operation of Protection Circuit The protection circuit, when connected, will remove current drive from the triac if an open or shorted sensor is detected. This circuit is activated by connecting Pin 13 to Pin 14 (see Figure 1). The following conditions should be observed when the protection circuit is utilized: a. The internal supply should be used and the external load current must be limited to 2 mA with a 5 kΩ dropping resistor. b. Sensor Resistance (R X ) and RP values should be between 2 kΩ and 100 kΩ . c. The relationship 0.33 < RX /RP < 3 must be met over the anticipated temperature range to prevent undesired activation of the circuit. A shunt or series resistor may have to be added. External Inhibit Function A priority inhibit command applied to Pin 1 will remove current drive from the thyristor. A command of at least +1.2 V @ 10 µA is required. A DTL or TTL logic 1 applied to Pin 1 will activate the inhibit function. DC Gate Current Mode When comparator operation is desired or inductive loads are being switched, Pins 7 and 12 should be connected. This connection disables the zero–crossing detector to permit the flow of gate current from the differential sensing amplifier on demand. Care should be exercised to avoid possible overloading of the internal power supply when operating the device in this mode. A resistor should be inserted between Pin 4 and the thyristor gate in order to limit the current.
