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.
