What is a battery backup switch-over circuit?
Real Time ClockFunction
These RTCs have a backup battery switch-over circuit which detects power failures and automatically switches to the battery supply when a power failure occurs. They are also equipped with two or three power supply pins so there is no need of adding a diode.
Notes: R2062 does not have the SW2 switch or the VSB pin. R2262 has the SW2 switch and the BAT pin instead of the VSB pin.
The SW2 switch is constantly turned on unless it is turned off by a register setting.
