ML4836*

Compact Fluorescent

Electronic Dimming Ballast Controller

GENERAL DESCRIPTION

FEATURES

The ML4836 is a complete solution for a dimmable or a

non-dimmable high efficiency electronic ballast especially

tailored for a compact fluorescent lamp (CFL). The

Bi-CMOS ML4836 contains controllers for dimming

ballast with end-of-life detection capability.

■ Programmable start scenario for rapid/instant start lamps

■ Triple frequency control network for dimming or

starting to handle various lamp sizes

■ Programmable restart for lamp out condition to reduce

The ballast controller section provides for programmable

starting sequence with individual adjustable preheat and

lamp out-of-socket interrupt times. The ML4836 provides

latch type shut down comparator for ballast controllers in

the event of end-of-life for the CFL.

ballast heating.

■ Internal over-temperature shutdown

■ Low start-up current; < 0.55mA
