UBA2080A

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: IO(sink) = 400 mA and IO(source) = 200 mA  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.
