FUNCTIONAL DESCRIPTION
The ML4836 consists of flexible ballast control section.
Start-up and lamp-out retry timing are controlled by the
selection of external timing components, allowing for
control of a wide variety of different lamp types. The
ballast section controls the lamp power using frequency
modulation (FM) with additional programmability
provided to adjust the VCO frequency range. This allows
for the IC to be used with a variety of different output
networks. Figure 1 depicts a detailed block diagram of
ML4836.
The ML4836 provides several safety features. See the
corresponding sections for more details:
End-of-lamp life detection to detect EOL and shut-off
lamps; See End Of Life Section.
Thermal shutdown for temperature sensing extremes;
See IC Bias, Under-Voltage Lockout and Thermal
Shutdown Section.
Relamping starting with anti-flash for programmable
restart for lamp out conditions while minimizing
“flashing” when powering from full power to dimming
levels; See Starting, Re-Start, Preheat and Interrupt
Section
