Preliminary specification
Full bridge driver IC
UBA2030T
Automotive application
The life of an HID lamp depends on the rate of sodium
migration through its quartz wall. To minimize this, the
lamp must be operated negative with respect to system
ground.
Figure 6 shows a full bridge with an HID lamp in an
automotive environment, and a control circuit referenced
to the high side of the bridge. The BER and HV pins are
connected to system ground. The bridge can be held in its
current state using the BE pin. See the timing diagram in
Fig.3.
