INTEGRATED CIRCUITS DATA SHEET UBA2000T Electronic TL-lamp starter Product specification File under Integrated Circuits, IC11 1996 Jan 03 Philips Semiconductors Product specification Electronic TL-lamp starter FEATURES Electronic starter, fully compatible with conventional glow-switch starters Reliable and instant ignition Accurate defined preheat time derived from the mains frequency Increased starter life since no mechanical parts are used No radio-interference (according to “IEC926 10.5”) Automatic reset after interruption of supply voltage Large operating temperature range: −40 to +85 °C Maximum current protection of the preheat current Ignition shut-off at end of lamp life; no overheating of load. ORDERING INFORMATION PACKAGE TYPE NUMBER NAME UBA2000T SO8 DESCRIPTION plastic small outline package; 8 leads; body width 3.9 mm GENERAL DESCRIPTION UBA2000T The UBA2000T is an integrated circuit for electronic TL-lamp starters and is fully compatible with conventional glow switch starters. The circuit controls the preheating and ignition of the lamp. The preheat time is well defined without spread, since it is derived from the mains frequency. When the lamp fails, ignition is shut-off after 7 ignition attempts. The circuit has an automatic reset when the supply voltage is interrupted.
