Care must be taken, especially when using an external power supply, that total package dissipation is not exceeded. Pulse Duration test.
However, the series resistor R S must have the indicated value, shown in Table A for the specified input voltage. Download CA Datasheet. Suggested dropping resistor R S values are given in the table below. Proportional control capability or hysteresis may be implemented using this block.
This synchronization eliminates RFI when used with resistive loads. Triac Drive — Supplies high—current pulses to the external power controlling thyristor. Protection Circuit — A built—in circuit may be actuated, if the sensor opens or shorts, to remove the drive current from the external triac.
Inhibit Capability — Thyristor firing may be inhibited by the action of an internal diode gate at Pin 1. 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.
