In many applications, it is desirable to have the ability to
detect a drop below, or rise above, a particular threshold.
For general battery applications, Figure 23-4 provides a
possible voltage curve.
Over time, the device voltage decreases. When the
device voltage reaches voltage, V
generates an interrupt at time, T
cause the execution of an ISR, which would allow the
application to perform “housekeeping tasks” and
perform a controlled shutdown before the device
voltage exits the valid operating range at T
The HLVD, thus, would give the application a time
window, represented by the difference between T
