ABSOLUTE MAXIMUM RATINGS
(*) The device has an internal Clamping Zener between GND and the V
CC
pin, it must not be supplied by
a Low Impedance Voltage Source.
Note: ESD immunity for pins 14, 15 and 16 is guaranteed up to 900V (Human Body Model)

EN2
Enable 2. EN2 input (active high) restarts the start-up procedure (preheating and ignition
sequence). This features is useful if the lamp does not turn-on after the first ignition sequence .
Ground.
Low Side Driver Output. This pin must be connected to the low side power MOSFET gate of the
half bridge. A resistor connected between this pin and the power MOS gate can be used to
reduce the peak current.
Supply Voltage. This pin, connected to the supply filter capacitor, is internally clamped (15.6V
typical).
Non Connected. This pin set a distance between the pins related to the HV and those related to
the LV side.
High Side Driver Floating Reference. This pin must be connected close to the source of the high
side power MOS or IGBT.
High Side Driver Output. This pin must be connected to the high side power MOSFET gate of the
half bridge. A resistor connected between this pin and the power MOS gate can be used to
reduce the peak current.
Bootstrapped Supply Voltage. Between this pin and VS must be connected the bootstrap capac-
itor. A patented integrated circuitry replaces the external bootstrap diode, by means of a high
voltage DMOS, synchronously driven with the low side power MOSFET.
