Notes :
1. d = 50 % the duty cycle of theoutputsignal atpin 6.
2. The lamp is switchedon witha fixed delay when the alternator voltage becomes higher than V
AH
. (overcharge indication).
3. Measured 100ms after turn-on.
4. The lamp is switched on with a fixed delay when the voltage V
p
becomes lowerthan V
PL
(thealternator is not charging the battery).
5. The lamp is switchedon when the cable B isbroken (V
- V
becomes higher than V
).
6. The lamp is switchedon when the cable A isbroken (IC without powervoltage supply).
7. When the voltage at pin 1 is greater than V
1 dp
the internal darlington of the lamp is switched off.
