DESCRIPTION
The TK65010 battery voltage monitor is designed for
portable battery powered systems where board space and
cost are important design considerations. The proprietary
monitoring architecture of the TK65010 allows two separate
warning thresholds to be set utilizing a single resistor
divider and single input pin.
The first warning indicator, a Low Battery Output (LBO), is
intended to warn the battery powered system of a low
battery condition. In such a condition, the LBO may be
used to alert the system to illuminate a low battery indicator
and to take appropriate action preparing for battery failure.

The second warning indicator, a Dead Battery Output
(DBO), is intended to be used by the system for shutdown
purposes. The availability of the DBO allows the system to
shut down in order to minimize deep discharge of the
battery.
The two warning indicators can be implemented utilizing
the TK65010 and only two external components.

The TK65010 is available in a miniature 5-pin SOT-23-5
surface mount package.
