C.1 Power Supplies
Power is supplied to the Intellicom board from an external source either through header J7
or from another Intellicom through header J5, the RJ-12 jack.
The Intellicom board itself is protected against reverse polarity by Shottky diodes at D6
and D7 as shown in Figure C-1. The Shottky diode has a low forward voltage drop, 0.3 V,
which keeps the minimum DCIN required to power the Intellicom lower than a normal sil-
icon diode would allow.
Capacitor C28 provides surge current protection for the voltage regulator, and allows the
external power supply to be located some distance away from the Intellicom board. A
switching power regulator is used. The input voltage range is from 9 V to 40 V.
