APPENDIX C. POWER MANAGEMENT
Appendix C describes the power circuitry distributed on the
Intellicom.
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.
Figure C-1. Intellicom Power Supply Schematic
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.
