UBA2033

INTEGRATED CIRCUITS DATA SHEET UBA2033 HF full bridge driver IC Product specification 2002 Oct 08 NXP Semiconductors HF full bridge driver IC Product specification UBA2033 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 voltage Bridge disable function Input for start-up delay Adjustable oscillator frequency Predefined bridge position during start-up. GENERAL DESCRIPTION The UBA2033 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 low-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 driver. APPLICATIONS The UBA2033 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.
