5. Protection Circuit — A built–in circuit may be
actuated, if the sensor opens or shorts, to remove the

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.

X
P
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.

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.
