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.

APPLICATION INFORMATION Power Supply 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. MOTOROLA ANALOG IC DEVICE DATA b. Sensor Resistance (RX) 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. 5 CA3059 OUTLINE DIMENSIONS PLASTIC PACKAGE CASE 646–06 ISSUE L 14 8 1 7 B A F L C J N H G D SEATING PLANE K M NOTES: 1.
