In indication as to whether load current is flowing or not
is provided by the triac itself. When the triac is ignited,
the voltage at electrode H
1
drops from the instantaneous
value of the mains voltage to approximately 1.5 V, the
value of the forward voltage of the triac. When the load
current drops below the hold current of the triac towards
the end of the half-cycle, V
H1
again returns to the instan-
taneous value of the mains voltage. The current detector
with its input at Pin 4 now controls this triac voltage and
blocks the pulse generator via G
1
and S
1
by increasing the
reference voltage as long as the triac is conducting. As, in
the case of a resistive load, the triac may be extinguished
shortly before the zero transition of the mains voltage –
when the load current drops below the hold current – the
RS flip-flop must prevent any possible second ignition
pulse from being generated.

Additional Function
An internal supply voltage control circuit insures that
output pulses can be generated only when the supply
voltage required for operation of all logic functions is
available.
