Ballast Control IC
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.
