2.7.2
If the duration of the bus undervoltage exceeds t > 800 ms (see
lockout (UVLO). The chip supply voltage drops below V
< 130 µA. When the Vcc voltage exceeds the 10.6 V threshold again, the IC current consumption is below I
< 160 µA. In that case, the controller resets the timer and restarts with the full start-up procedure, including
monitoring, power-up, start-up, soft start, preheating, ignition, pre-run and run modes, as shown in

2.8
In order to decrease the final ballast testing time for customers, the 2nd generation of ballast IC supports an
integrated built-in Customer Test Mode and several functions to disable some features and states of the IC.
2.8.1
This feature forces the IC to stay in the preheating mode (see
without any preheating (see
Normally, the preheating phase is in a range of 0 ms up to 2500 ms set via a resistor R
