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.
