Philips Semiconductors

Full bridge driver IC

Preliminary specification

UBA2030T

FEATURES

• Full bridge driver

• Integrated bootstrap diodes

• Integrated high voltage level shift function

• High voltage input (570 V maximum) for the internal

supply

• Adjustable ‘dead time’

• Adjustable oscillator frequency

• High voltage level shifter for the bridge enable function

• Shut-down function.

GENERAL DESCRIPTION

The UBA2030T is a high voltage integrated circuit

fabricated using the BCD750 power logic process.

The circuit is designed for driving the MOSFETs in a full

bridge configuration. In addition, it features a shut-down

function, an adjustable oscillator and a PMOS high voltage

level shifter to control the bridge enable function.

To guarantee an accurate 50% duty factor, the oscillator

signal passes through a divider before being fed to the

output drivers.

APPLICATIONS

• The UBA2030T can drive the MOSFETs in any type of

load configured as a full bridge

• The circuit is intended as a commutator for High

Intensity Discharge (HID) lamps.
