RabbitCore RCM2100
A lithium battery with a nominal voltage of 3 V and a minimum capacity of 165 mAh is
recommended. A lithium battery is strongly recommended because of its nearly constant
nominal voltage over most of its life.
The drain on the battery by the RCM2100 is typically 16 A when no other power is sup-
plied. If a 950 mAh battery is used, the battery can last more than 6 years:
The actual life in your application will depend on the current drawn by components not on
the RCM2100 and the storage capacity of the battery. Note that the shelf life of a lithium
battery is ultimately 10 years.
The battery-backup circuit serves three purposes:
It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting
the current consumed 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.
A voltage, VOSC, is supplied to U7, which keeps the 32.768 kHz oscillator working
when the voltage begins to drop.
VRAM and Vcc are nearly equal (<100 mV, typically 10 mV) when power is supplied to
the RCM2100.
Figure C-2 shows the RCM2100 battery-backup circuit.
