NOTES

1. The supply current is 0.45 x (RMS current fed into pin 2). I5 is the current drained from pin 5 externally. I4AV is the average triac

gate current supplied each mains cycle.

2. Triac firing pulse. tp Pulse width = 0.69 R6CD microseconds typical

tf Pulse finish = 1.09 R6CD microseconds minimum after zero voltage point R6 in kohms. CD in nF.

See Application circuit

tp Nominal (CD = 2.7nF) = 50 microseconds

tp Minimum (CD = 2.7nF) = 63 microseconds

3. Ramp period = 0.85 ± 0.15 x RTCT sec. See Application circuit. The actual value of Rt must lie between 500kohms and 3Mohms.
