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.
n Full bridge driver circuit
n Integrated bootstrap diodes
n 464 V integrated high voltage level shift function to drive HID lamps below ground level
n 550 V series regulator input to make the internal supply
n 550 V maximum bridge voltage
n Accurate bridge disable function
n Input for start-up delay
n Adjustable oscillator frequency
n Selectable frequency divider
n Predefined bridge position during start-up
n Adaptive non-overlap
The UBA2036 can drive (via the power MOSFETs) any kind of load in a full bridge
configuration
The circuit is especially designed as a commutator controller for HID lamps in car
headlights, projectors and general lighting applications
