Ignition (time interval B Figure 5)
When the voltage at pin TCH drops down to 1.50V (typ.), the pin EOI is driven in high
impedance state and CIGN is exponentially charged according to the time constant τ given
by CIGN*RPRE that defines the ignition time and the frequency shift starts.
The ignition time is the time necessary to EOI voltage to reach 1.9V, so, by means of simple
calculation:
Equation 3
During this phase, the half-bridge current control can limit the maximum voltage applied
to the lamp by forcing small frequency increases whenever the half-bridge sense resistor
voltage exceeds the HBCSH threshold (see the “Half-Bridge current control” paragraph).
Figure 5, centre and right, shows the L6585D behavior as the lamp gets older; if it doesn’t
ignite for a time longer than the pre-heating one (counted by a cycle charge/discharge of the
TCH pin), the IC is stopped, enters low consumption and waits for either a re-lamp or an
UVLO.
