Enable/Disable Configuration
The HV830 can be easily enabled and disabled via a logic control
signal on the R
SW
and R
EL
resistors as shown in Figure 2 below.
The control signal can be from a microprocessor. R
SW
and R
EL

peres will be drawn from the logic signal when it is at a logic high
(enable) state. When the microprocessor signal is high the
device is enabled and when the signal is low, it is disabled.
Split Supply Configuration Using a Single
Cell (1.5V) Battery
The HV830 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 3. The regulated voltage can
be used to run the internal logic of the HV830. 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 HV830
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 2.
Split Supply Configuration for Battery
Voltages of Higher than 9.5V
Figure 3 can also be used with high battery voltages such as 12V
as long as the input voltage, V
DD
, to the HV830 device is within
its specifications of 2.0V to 9.5V.
