DESCRIPTION
GENERAL DESCRIPTION
The UBA2033 is a high voltage monolithic integrated
circuit made in the EZ-HV SOI process. The circuit is
designed for driving the MOSFETs in a full bridge
configuration. In addition, it features a disable function, an
internal adjustable oscillator and an external drive function
with a low-voltage level shifter for driving the bridge.
To guarantee an accurate 50% duty factor, the oscillator
signal can be passed through a divider before being fed to
the output driver.
