Data Sheet
Ag1170
+5V / +3.3V LOW POWER RINGING SLIC
4.0 Switch Hook Detect Level
When the subscriber goes “off-hook” loop current will
begin to flow. If this current is above the detection
threshold (10mA) the switch hook output, SHK, will
switch to a logic 1. It is recommended that software or
hardware de-bouncing of the switch hook signal is
used. This is to avoid short pulses which can cause a
false switch hook output, triggering the incorrect
system response.
During loop disconnect dialling, SHK will pulse
between logic 1 and logic 0 to indicate the digits being
dialled. Again it is recommended that software de-
bouncing is used to avoid false detection of digits.
5.0 Protection of the Ag1170 SLIC
5.1 Thermal Protection
Should the SLIC be operated incorrectly, for example
by accidentally shorting Tip and Ring to each other or
to ground, the power dissipation is automatically limited
by the DC/DC converter
This feature means that the SLIC will always operate
within its power limits, without overheating. When
operating on very short lines the battery voltage is
regulated to a low value. This limits the power
dissipation and ensures the Ag1170 operates with a
minimum temperature rise.
