1. General description

The UBA2037 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 UBA2037 is especially suitable for High Intensity Discharge (HID) lamp drivers for

projectors and general lighting applications.

2. Features

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

3. Applications

n The UBA2037 can drive (via the power MOSFETs) any kind of load in a full bridge

conﬁguration.

n The circuit is especially designed as a commutator controller for HID lamps in

projectors and general lighting applications.
