Configuration 2 illustrates the DS1305 being backed up by a rechargeable energy source. In this case, the
VBAT pin is grounded, VCC1 is connected to the primary power supply and VCC2 is connected to the
secondary supply (the rechargeable energy source). The DS1305 will operate from the larger of VCC1 or
VCC2. When VCC1 is greater than VCC2 + 0.2 volt (typical), VCC1 will power the DS1305. When VCC1 is
less than VCC2, VCC2 will power the DS1305.
The DS1305 does not write protect itself in this
configuration.
Configuration 3 shows the DS1305 in battery operate mode where the device is powered only by a single
battery. In this case, the VCC1 and VBAT pins are grounded and the battery is connected to the VCC2 pin.
Only these three configurations are allowed. Unused supply pins must be grounded.
