Rev. 1.1 — 6 December 2011
Objective data sheet
1. General description
The UBA2080 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
Integrated half-bridge driver circuit
Integrated bootstrap diode
Maximum voltage of 600 V
Output driver capability: IO(sink) = 400 mA and IO(source) = 200 mA
Maximum frequency 800 kHz
UBA2080:
Outputs in phase with inputs
UBA2081:
Adjustable dead-time
Shutdown input
3. Applications
Driver (via external MOSFETs) for any kind of load in a half-bridge configuration
