INTEGRATED CIRCUITS DATA SHEET UBA2032 Full bridge driver IC Preliminary specification 2002 Oct 07 Philips Semiconductors Preliminary specification Full bridge driver IC 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. 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. ORDERING INFORMATION TYPE NUMBER UBA2032T UBA2032TS PACKAGE NAME SO24 SSOP28 DESCRIPTION plastic small outline package; 24 leads; body width 7.5 mm plastic shrink small outline package; 28 leads; body width 5.3 mm GENERAL DESCRIPTION UBA2032 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. VERSION SOT137-1 SOT341-1 2002 Oct 07 2 Philips Se...
