LIC01 Series

LIGHT IGNITION CIRCUIT
The LIC01 has been especially designed for high
voltage pulse generation circuits such as light
ignitors for :
. High pressure sodium lamp
. Lamp flashing circuit
. Metal Halid lamp
It uses a high performance planar diffused technol-
ogy device suitable for high surge current opera-
tion in rugged environmental conditions.
When the voltage across the device reaches the
breakover voltage, it decreases from an off-state
to low voltage on-state condition. When the current
through the circuit drops below the holding current
I
H
, the device comes back to the off-state.

TYPICAL APPLICATION
When the peak voltage across C1 reaches the
break over voltage VBO of the LIC01, this device
turns on and produces a pulse of current through
the primary of the transformer. In turn, the trans-
former generates high voltage pulses across the
lamp.
