This chart gives the range of voltages which can be applied to the terminals listed horizontally with respect to the terminals listed vertically. For example, the voltage range of horizontal Terminal 6 to vertical Terminal 4 is 2V to -10V. NOTES: 1. Resistance should be inserted between Terminal 5 and external supply or line voltage for limiting current into Terminal 5 to less than 50mA. 2. Resistance should be inserted between Terminal 14 and external supply for limiting current into Terminal 14 to less than 2mA. 3. For the CA3079 indicated terminal is internally connected and, therefore, should not be used. 4. Voltages are not normally applied between these terminals; however, voltages appearing between these terminals are safe, if t he spec- ified voltage limits between all other terminals are not exceeded. 5.

The internal supply is designed to allow for some current to be drawn by the auxiliary power circuits. Typical power supply characteristics are given in Figures 2(b) and 2(c). Power Supply Considerations for CA3059 The output current available from the internal supply may not be adequate for higher power applications. In such applica- tions an external power supply with a higher voltage should be used with a resulting increase in the output level. (See Figure 4 for the peak output current characteristics.) When an external power supply is used, Terminal 5 should be con- nected to Terminal 7 and the synchronizing voltage applied to Terminal 12 as illustrated in Figure 5(a). Operation of Built-In Protection for the CA3059 A special feature of the CA3059 is the inclusion of a protec- tion circuit which, when connected, removes power from the load if the sensor either shorts or opens. The protection cir- cuit is activated by connecting Terminal 14 to Terminal 13 as shown in the Functional Block Diagram. To assure proper operation of the protection circuit the following conditions should be observed: 1. Use the internal supply and limit the external load current to 2mA with a 5kΩ dropping resistor. 2. Set the value of R P and sensor resistance (RX) between 2kΩ and 100kΩ. 3. The ratio of R X to RP, typically, should be greater than 0.33 and less than 3. If either of these ratios is not met with an unmodified sensor over the entire anticipated temperature range, then either a series or shunt resistor must be added to avoid undesired activation of the circuit. If operation of the protection circuit is desired under condi- tions other than those specified above, then apply the data given in Figure 12. External Inhibit Function for the CA3059 A priority inhibit command may be applied to Terminal 1. The presence of at least +1.2V at 10 µA will remove drive from the thyristor. This required level is compatible with DTL or T 2L logic. A logical 1 activates the inhibit function. DC Gate Current Mode for the CA3059 Connecting Terminals 7 and 12 disables the zero-crossing detector and permits the flow of gate current on demand from the differential sensing amplifier. This mode of opera- tion is useful when comparator operation is desired or when inductive loads are switched. Care must be exercised to avoid overloading the internal power supply when operating in this mode. A sensitive gate thyristor should be used with a resistor placed between Terminal 4 and the gate in order to limit the gate current. Dimensions in parentheses are in millimeters and are derived from the basic inch dimensions as indicated. Grid gradations are in mils (10-3 inch). The photographs and dimensions represent a chip when it is par of the wafer. When the wafer is cut into chips, the cleavage angles are 57o instead of 90o with respect to the face of the chip. Therefore, the isolated chip is actually 7 mils (0.17mm) larger in both dimensions. Operating Considerations
