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 conguration. 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.
