Proportional-control triac triggering circuit
Product specification
TDA1023/T
Trigger pulse width control input PW (pin 10)
The width of the trigger pulse may be adjusted to the value
required for the triac by choosing the value of the external
synchronization resistor RS between the trigger pulse
width control input PW (pin 10) and the AC mains.
The pulse width is inversely proportional to the input
current (see Fig.13).
Output Q (pin 3)
Since the circuit has an open-emitter output it is capable of
sourcing current. It is thus suited for generating
positive-going trigger pulses. The output is current-limited
and short-circuit protected. The maximum output current is
150 mA and the output pulses are stabilized at 10 V for
output currents up to that value.
To minimize the total supply current and power dissipation,
a gate resistor RG must be connected between the output
Q and the triac gate to limit the output current to the
minimum required by the triac (see Figs 5 to 8).
Pull-down resistor Rpd (pin 1)
The TDA1023 includes a 1.75 kΩ pull-down resistor Rpd
between pins 1 and 13 (VEE, ground connection) intended
for use with sensitive triacs.
