Split Supply Configuration Using a Single
Cell (1.5V) Battery
The HV803 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 HV803. The amount of
current necessary to run the internal logic is typically 30 to 60
μ
A.
Therefore, the regulated voltage could easily provide the current
without being loaded down. The HV803 used in this configura-
tion 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 HV803 device is within
its specifications of 2.4V to 9.5V.
