Overview
The IHPC is an integrated power controller especially designed for feeding two-wire
ISDN-transmission lines. One line can be powered by one IHPC. An external resistor
defines the value of the current-limit for the line. Powering can be switched on or off by
the logic inputs “PFEN” and “PFENQ”. With a logic low at the “APFI” output the IHPC
signals that current-limiting is active; this signal is low-pass filtered. An external capacitor
defines the corner frequency of this low-pass filter and the resulting delay time
respectively. A second external capacitor is needed to make sure that longitudinal
disturbances (AC) will not produce a current limiting effect. Line current-limiting and
reducing this limiting level in case of overtemperature guards the IHPC against
overloads.
