GENERAL DESCRIPTION
UBA2030T
The UBA2030T is a high voltage integrated circuit
fabricated using the BCD750 power logic process. The
circuit is designed for driving the MOSFETs in a full bridge
configuration. In addition, it features a shut-down function,
an adjustable oscillator and a PMOS high voltage level
shifter to control the bridge enable function. To guarantee
an accurate 50% duty factor, the oscillator signal passes
through a divider before being fed to the output drivers.
