Application with negative lamp voltage
The life of an HID lamp depends of the rate of sodium
migration through the quartz wall of the lamp. To minimize
this, the lamp must operate negative with respect to the
system ground. Figure 7 shows a full bridge with an HID
lamp, along with a control circuit referenced to the system

negative voltages with respect to the system ground.
Pin +LVS and pin HV can be connected to the same
supply as the control unit The output state of the bridge is
related to the position of pin EXTDR. See also the timing
