UBA2036TS Full bridge control IC for HID automotive lighting Rev. 01 — 30 October 2008 Product data sheet 1. General description The UBA2036 is a high voltage monolithic Integrated Circuit (IC) manufactured in a High Voltage Silicon On Insulator (HVSOI) process. This circuit is designed for driving MOSFETs in a full bridge configuration. In addition, it features a disable function, an internal adjustable oscillator and an external clock input function with a high-voltage level shifter for driving the bridge. To guarantee an accurate 50 % duty cycle, the oscillator signal can be passed through a divider before being fed to the output drivers. The UBA2036 is especially suitable for High Intensity Discharge (HID) lamp drivers for car headlights, projectors and general lighting applications. 2. Features I Full bridge driver circuit I Integrated bootstrap diodes I 464 V integrated high voltage level shift function to drive HID lamps below ground level I 550 V series regulator input to make the internal supply I 550 V maximum bridge voltage I Accurate bridge disable function I Input for start-up delay I Adjustable oscillator frequency I Selectable frequency divider I Predefined bridge position during start-up I Adaptive non-overlap 3. Applications I The UBA2036 can drive (via the power MOSFETs) any kind of load in a full bridge configuration I The circuit is especially designed as a commutator controller for HID lamps in car headlights, projectors and general lighting applications 4.
