2.8.3 Built in Customer Test Mode (Clock Acceleration)
The built in customer test mode, supported by this IC, saves testing time for customers in terms of
ballast end test. In that mode, the IC accelerates the internal clock in order to reduce the time of the 4
different procedures by the following factors (see Table 1).

mode before powering up. This status is hold as long as the voltage at the RES pin is at V
up to 5.0 V (± 5 %) – no power up. Note: after the activation of the clock acceleration mode, the
voltage level of 5.0V at the Run Frequency and Preheating Frequency pin (V

In order to start the IC with an accelerated clock, set the voltage at the RES pin to GND (V
Figure 34 Clock Acceleration (Built in Customer Test Mode). The IC powers up the system and starts
working with an accelerated clock. Now the duration of the different modes are accelerated by Factors
shown in Table 1.
