DS32kHz
below a certain level compared to V
, the device switches over to V
. (See Figure 1.0.) This mode
BAT
BAT
uses V
to conserve the battery connected to V
while V
is applied.
CC

In the single-supply mode, V
is grounded and the unit is powered by V
. Current consumption is less
CC
BAT
than that of V
, because the comparator circuit is unpowered. (See Figure 2.0.)

Figure 1.0 shows how the DS32kHz should be connected when using two power supplies. V
should be
CC
between 4.5V and 5.5V and V
should be between 2.7V and 3.3V. Figure 2.0 shows how the DS32kHz
BAT
can be used when only a single-supply system is available. V
should be grounded and V
should then
CC
BAT
be held between 2.7V and 5.5V. The V
pin should be connected directly to a battery using no external
BAT
components.
