R2051 Series
G
Connection of /INTR and /VDCC Pin
The /INTR and /VDCC pins follow the N-channel open drain output logic and contains no protective diode on the
power supply side. As such, it can be connected to a pull-up resistor of up to 5.5 volts regardless of supply
voltage.

*1) Depending on whether the /INTR and /VDCC
pins are to be used during battery backup, it
should be connected to a pull-up resistor at
the following different positions:
(1) Position A in the left diagram when it is not to
be used during battery backup.
(2) Position B in the left diagram when it is to be
used during battery backup.
