PT5615
Ballast Control IC
DESCRIPTION
The PT5615 is a ballast control IC, with the 650V
half-bridge driver and full protections, designed to drive
all types of fluorescent lamps. The features such as
programmable
preheat
time
and
frequency,
programmable and precise run frequency, self-adapting
ignition time regulator and auto-restart for lamp
replacement, provide a high degree of flexibility for the
ballast design engineers. The protection features
include the filaments detection, ignition failure and
end-of-life protection for lamp and the over-current
protection for half bridge. It is easy to provide a
protection for multi-lamp application. The PT5615 is
available in both DIP16 and SOP16 packages.
