5 / 19 page May 1991 5 Philips Semiconductors Product specification Proportional-control triac triggering circuit 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 k Ω pull-down resistor R pd between pins 1 and 13 (VEE, ground connection) intended for use with sensitive triacs.
