APPLICATION INFORMATION
Basic application
A basic full bridge configuration with an HID lamp is shown
in Fig.4. The bridge enable and shut-down functions are
not used in this application. The EXO, BE, BER and
SD pins are connected to system ground. The IC is
powered by the high voltage supply.

supply voltage exceeds the ‘start oscillating threshold’
(typically 15.5 V). If the supply voltage at the HV pin falls
below the ‘stop oscillating threshold’ (typically 13 V), the
