te c Notes : 1. d = 50 % the duty cycle of the output signal at pin 6.

le u 2. The lamp is switched on with a fixed delay when the alternator voltage becomes higher than VAH. (overcharge indication).

d 3. Measured 100 ms after turn-on.

so ro 4. The lamp is switched on with a fixed delay when the voltage Vp becomes lower than VPL (the alternator is not charging the battery).

5. The lamp is switched on when the cable B is broken (VA - VS becomes higher than VAS).

b P 6. The lamp is switched on when the cable A is broken (IC without power voltage supply).

OObsolete 7. When the voltage at pin 1 is greater than V1 dp the internal darlington of the lamp is switched off.
