2.4 Speech mode
In speech mode (Ring relay in position 1), the
protection is provided by the combination of both
CLP30-200B1 and the external voltage reference
device (for example LCP1511D).
In normal conditions, the working point of this
circuit is located in region 4 of
A2
curve :
the CLP30-200B1 is idle.
When a surge occurs on the line, the external
voltage reference device clamps at GND or -V
bat
respectively for positive and negative surges. This
generates a current which is detected by R
SENSE
and causes the protection to act : the line is
short-circuited to GND. The operating point moves
to region 6 for positive surges or region 5 for
negative surges.
