Enable/Disable Configuration
The HV830 can be easily enabled and disabled via a logic
control signal on the RSW and REL resistors as shown in Fig.2
below. The control signal can be from a microprocessor. RSW
and REL are typically very high values, therefore, only 10’s
of microamperes 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.
