NOTES: 1. Care must be taken, especially when using an external power supply, that total package dissipation is not exceeded.
2. The values given in the Electrical Characteristics Table at 120 V also apply for operation at input voltages of 24 V, 208/230 V, and 277 V, except for
Pulse Duration test. However, the series resistor (R ) must have the indicated value, shown in Table A for the specified input voltage.

APPLICATION INFORMATION
Power Supply
b. Sensor Resistance (R ) and R values should be
X
P
between 2 kΩ and 100 kΩ.
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.
c. The relationship 0.33 < R /R < 3 must be met over
X
P
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.
Operation of Protection Circuit
DC Gate Current Mode
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:
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.
a. The internal supply should be used and the external
load current must be limited to 2 mA with a 5 kΩ
dropping resistor.
