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.

7.4 UBA2081 non-overlap time
The external resistor (RSD) on pin SD sets the non-overlap time of the UBA2081. The
relationship between this resistor value and actual dead-time is listed in Figure 6.
It is essential to add a 10 nF to 100 nF decoupling capacitor across RSD to ensure a noise
immune dead-time system.

7.5 UBA2081 shutdown protection
When the voltage at pin SD is pulled below VIH, the internal sink drivers of the pins GL and
GH are immediately enabled to switch off the external power MOSFETs.
The shutdown comparator has a hysteresis of Vhys(SD) to avoid multiple switching.
Preferably, pin SD is pulled low via a collector of a transistor (see application schematic)
to avoid loading of this pin (Influences the non-overlap time settings) at normal operation.
7.6 UBA2080 overlap protection
The internal logic takes care that the GL driver and GH driver are both set to LOW in this
situation to avoid that HIN = LIN = 1 causes a cross current in the external half-bridge.
7.7 UBA2080A select function
Pin SEL enables the selection of either the UBA2080 or the UBA2081 functionality.
SEL = 0 gives the UBA2080 functionality. SEL = VDD gives the UBA2081 functionality.
