Table 2. Input and Output Status in Battery-Backup Mode; to enter the Battery-Backup Mode, V CC must be less than the
reset threshold and less than V BATT .
Input Supply Voltage
The Input Supply Voltage (V CC ) should be a
regulated +5V source. V CC connects to V OUT
V BATT
V CC
via a parallel diode and a large PMOS switch.
The switch carries the entire current load for
currents less than 250mA. The parallel diode
SW1
D1
D2
SW2
carries any current in excess of 250mA. Both
the switch and the diode have impedances
less than 1 ? each. Refer to Figure 24 . The
maximum continuous current is 250mA, but
V OUT
0.1 μ F
power-on transients may reach a maximum of 1A.
Backup-Battery Input
The Backup-Battery Input (V BATT ) is similar
Figure 24. V CC and V BATT to V OUT Switch
to V CC , except the PMOS switch and parallel
diode are much smaller. Refer to Figure 24 .
Accordingly, the on-resistances of the diode and
the switch are each approximately 10 ? .
