Full bridge driver IC

Preliminary specification

UBA2032

FEATURES

• Full bridge driver circuit

• Integrated bootstrap diodes

• Integrated high voltage level shift function

• High voltage input for the internal supply voltage

• 550 V maximum bridge voltage

• Bridge disa‘ble function

• Input for start-up delay

• Adjustable oscillator frequency

• Predefined bridge position during start-up

• Adaptive non-overlap.

GENERAL DESCRIPTION

The UBA2032 is a high voltage monolithic integrated

circuit made in the EZ-HV SOI process. The circuit is

designed for driving the MOSFETs in a full bridge

configuration. In addition, it features a disable function, an

internal adjustable oscillator and an external drive function

with a high-voltage level shifter for driving the bridge.

To guarantee an accurate 50% duty factor, the oscillator

signal can be passed through a divider before being fed to

the output drivers.

APPLICATIONS

• The UBA2032 can drive (via the MOSFETs) any kind of

load in a full bridge configuration

• The circuit is especially designed as a commutator for

High Intensity Discharge (HID) lamps.
