APPLICATION INFORMATION
Basic application
A basic full bridge configuration with an HID lamp is shown
in Fig.5. The bridge disable, the start-up delay and the
external drive functions are not used in this application.
The pins LVS, +LVS, EXTDR and BD are short-circuited
to SGND. The internal oscillator is used and to realise a
50% duty cycle the internal divider function has to be used
by connecting pin DD to pin SGND.

The IC is powered by the high voltage supply. Because
the internal oscillator is used, the bridge commutating
frequency is determined by the values of R
The bridge starts oscillating when the HV supply voltage
exceeds the level of release power drive (typically 12.5 V
on pin HV). If the supply voltage on pin HV drops below the
reset level of power drive (typically 10 V on pin HV), the
UBA2032 enters the start-up state.
