Intellicom (OP6600/OP6700)
C.2 Batteries and External Battery Connections
A battery board with a 1000 mAh lithium coin cell provides power to the real-time clock
and SRAM when external power is removed from the circuit. This allows the Intellicom to
continue to keep track of time and preserves the SRAM memory contents.
Figure C-2 shows the battery-board circuit.
Figure C-2. Intellicom Backup-Battery Board
Alternatively, starting with the 175-0206 version of the Intellicom, there is provision to
add a soldered-in battery directly on the Intellicom board.
The drain on the battery is typically less than 20 A when there is no external power
applied. The battery can last more than 5 years:
The drain on the battery is typically less than 4 A when external power is applied. The
battery can last for its full shelf life:
Since the shelf life of the battery is 10 years, the battery can last for its full shelf life when
external power is applied to the Intellicom.
C.2.1 Battery-Backup Circuit
The battery-backup circuit serves two purposes:
It reduces the battery voltage to the real-time clock, thereby reducing the current con-
sumed by the real-time clock and lengthening the battery life.
It ensures that current can flow only out of the battery to prevent charging the battery.
