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.
