The IC effectively provides continuous moni- toring of battery condition by pulse- sampling the system voltage at prede- termined intervals. Low standby cur- rent permits unswitched connection to the battery with minimal impact on operating life. The ability to load the battery during the test pulse provides assurance that sufficient reserve capac- ity exists to operate critical system components. The CS2516 contains an internal timer that generates a 1.0 millisecond test pulse once each 33 seconds (both times are typical). The load switch transistor conducts only during the test pulse, and can sink up to 50mA directly. An external transistor can be added to in- crease the load current capability. Should, during the test pulse, the sense terminal voltage fall below the thresh- old level determined by the internal (synthesized) temperature compensat- ed zener diode, the comparator will permit a charging current to flow out of PW. This pin is also the input of a Schmitt trigger that in turn drives the output transistor. Collectively, the charge current and trigger, in conjunc- tion with an external RC network, operate as a Òpulse-stretcherÓ to pro- vide output ÒONÓ times that are a multiple of the sampling time. This feature permits low battery alarm devices or visible annunciators to be driven directly by the IC. The maxi- mum permissible output current is 30mA.
