APPLICATIONS
The ADM9261 is designed for use in pagers and other
portable devices that use 3.3V logic systems derived from
a 9V battery. Interfacing of the ADM9261 to the system
will vary with the application, if a microcontroller is used,
the outputs of the ADM9261 may be connected to one or
more I/O lines. If a microprocessor is used with a separate
ASIC or other chip for I/O then the ADM9261 can be

interfaced to this. In either case the ADM9261 is very
simple to use. Inputs SU1 to SU3 are simply connected to
the supplies to be monitored and the outputs are con-
nected to the devices logic system, either separately or to a
single input using wired AND. The ADM9261 will derive
its power supply from one of the 3.3V supplies.
Figure 14 shows a typical application of the ADM9261.
