FUNCTIONAL BLOCK
DESCRIPTION
1.
Limiter–Power Supply
—
Allows operation of
the CA3059 directly from an AC line. Suggested
dropping resistor (R
S
) 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.
