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.
