UBA2080 UBA2080A UBA2081 Half-bridge driver IC Rev. 3 18 June 2012 Product data sheet 1. General description The UBA2080(A) and UBA2081 are high voltage monolithic integrated circuits made using the latch-up free Silicon-On-Insulator (SOI) process. The circuit is designed for driving MOSFETs in a half-bridge configuration. 2. Features and benefits Latch-up free and robust half bridge driver Output driver capability: I = 400 mA and I = 200 mA O(sink) O(source) Maximum frequency 800 kHz UBA2080: Outputs in phase with HIN and LIN inputs Overlap protection UBA2081: Outputs in phase with CLK input Adjustable dead-time Low active shutdown input 3. Applications Driver (via external MOSFETs) for any kind of load in a half-bridge configuration UBA2080A: Selectable between UBA2080 and UBA2081 functionality Thermally enhanced package for high frequency operation. 4.
