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 Fig. 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 100µA
at a VDD 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 RSW and REL resistors as shown
in Fig.2.
Split Supply Configuration for Battery Voltages of Higher than 9.5V
Fig. 3 can also be used with high battery voltages, such as is within its specifications of 2.0V to 9.5V.
