Preliminary specification
Full bridge driver IC
UBA2030T
Additional application information
The UBA2030T is the commutator part in a complete
system for driving an HID lamp. The life of the HID lamp
can depend on the amount of sodium that migrates
through its quartz wall. To minimize this migration, the
lamp must be operated negative with respect to system
ground.
Figure 7 shows a full bridge with an HID lamp in a typical
automotive configuration using a control unit referenced to
the high side of the bridge. Pin BER is connected to
system ground. The bridge can be held in its current state
by pin BE. The supply current to the internal low voltage
circuit is fed to pin HV which can be connected to either
system ground or to a low voltage DC supply, such as a
battery, as indicated by the dotted lines in Fig.7.
The diode in series with the supply to pin HV prevents C
i
being discharged if the lamp is shorted during the ignition
phase. C6 should be positioned as close as possible to
pin DTC. The control unit drives the MOSFETs relatively
hard which can cause radiation. To prevent switching the
MOSFETs hard, a resistor can be connected in series with
each gate.
In all applications, the voltage on pin HV must not be
allowed to become lower than the voltage at pin V
DD
during the start-up phase or during normal operation,
otherwise the full bridge will not operate correctly. During
the start-up phase, pin EXO and pin SD should both be
LOW. The voltage as a function of time at pin EXO and
pin SD should be >5 V/ms.
