The CA3059 and CA3079 zero-voltage switches are mono-
lithic silicon integrated circuits designed to control a thyristor
in a variety of AC power switching applications for AC input
voltages of 24V, 120V, 208/230V, and 277V at 50Hz-60Hz
and 400Hz. Each of the zero-voltage switches incorporates
4 functional blocks (see the Functional Block Diagram) as
follows:
1. Limiter-Power Supply - Permits operation directly from an
AC line.
2. Differential On/Off Sensing Amplifier - Tests the condition
of external sensors or command signals. Hysteresis or
proportional-control capability may easily be implement-
ed in this section.
3. Zero-Crossing Detector - Synchronizes the output pulses
of the circuit at the time when the AC cycle is at zero volt-
age point; thereby eliminating radio-frequency interfer-
ence (RFI) when used with resistive loads.
4. Triac Gating Circuit - Provides high-current pulses to the
gate of the power controlling thyristor.
In addition, the CA3059 provides the following important
auxiliary functions (see the Functional Block Diagram).
1. A built-in protection circuit that may be actuated to remove
drive from the triac if the sensor opens or shorts.
2. Thyristor firing may be inhibited through the action of an
internal diode gate connected to Terminal 1.

3. High-power dc comparator operation is provided by over-
riding the action of the zero-crossing detector. This is ac-
complished by connecting Terminal 12 to Terminal 7.
Gate current to the thyristor is continuous when Terminal
13 is positive with respect to Terminal 9.
The CA3059 and CA3079 are supplied in 14 lead dual-in-
line plastic packages.
