until the VB-to-VS voltage exceeds the high-side UVLO rising threshold, V BSUV+ (9 V, typical), and the high-
side driver is enabled. The capacitor CVCC should be large enough such that VCC does not reach UVLO-
before HO is enabled and the charge pump supply takes over.
External gate drive resistors, RHO and RLO, are also recommended as standard design practice to limit high
peak currents that can flow into or out of the HO and LO gate drive outputs.
During UVLO Mode, the high-side gate driver output, HO, is ‘low’ and the VCO pin is pulled down internally
to COM. The low-side gate driver output, LO, is open circuit and is used as a shutdown/reset input function
for automatically restarting the IC when a lamp has been removed and re-inserted. The IC includes an
internal shutdown threshold, V LOSD+ (8.75 V, typical), and re-start logic circuit at the LO pin that is only
active during UVLO mode. If VCC is above V CCUV+ , but the lamp is removed, the external pull-up network
(RLMP1 and RLMP2) will pull LO above V LOSD+ and the IC will remain in UVLO mode. When the lamp is re-
inserted, the lower filament of the lamp will pull LO down below V LOSD- (8.5 V, typical) and the IC will exit
UVLO Mode and enter Preheat/Ignition Mode.
Preheat/Ignition (PH/IGN) Mode
When VCC exceeds V CCUV+ and the LO pin is below V LOSD- , the IC enters Preheat/Ignition Mode. An internal
current source, I VCO (1 μ A, typical), (Figure 2) charges the external capacitor on pin VCO causing the voltage
on pin VCO to start ramping up linearly. An additional quick-start current, I VCOQS (50 μ A, typical), is also
connected to the VCO pin and charges the VCO pin initially to 0.85 V. The quick-start current charges the
VCO voltage up quickly to the internal 1 to 5 V range of the internal VCO. When the VCO voltage exceeds
0.85 V the quick-start current is then disconnected internally and the VCO voltage continues to charge up
with the normal frequency sweep current source, I VCO (1 μ A, typical) (Figure 3).

The frequency ramps down from the maximum frequency towards the resonance frequency of the high-Q
ballast output stage. The lamp filaments are preheated as the lamp voltage and load current increase. The
voltage on pin VCO continues to increase and the frequency keeps decreasing until the lamp ignites. If the
lamp ignites successfully, the IC will then enter DIM Mode (Figure 3).
