HV823
Split Supply Configuration Using a Single
Cell (1.5V) Battery
The HV823 can also be used for handheld devices operating
from a single cell 1.5V battery where a regulated voltage is
available. This is shown in Figure 5. The regulated voltage
can be used to run the internal logic of the HV823. The
amount of current necessary to run the internal logic is
typically 100
μ
A at a V
DD
of 3.0V. Therefore, the regulated
voltage could easily provide the current without being loaded
down. The HV823 used in this configuration can also be
enabled/disabled via logic control signal on the R
SW
and R
EL
resistors as shown in Figure 4.
Split Supply Configuration for Battery
Voltages of Higher than 9.5V
Figure 5 can also be used with high battery voltages such as 12V
as long as the input voltage, V
DD
, to the HV823 device is within
its specifications of 2.0V to 9.5V.

*Larger values may be required depending upon supply impedance.
