CS2516 General Description
The CS2516 is designed for use in battery powered medical, security, or environmental systems where prior notification of impending power source failure is a requirement. The IC effectively provides continuous monitoring of battery condition by pulsesampling the system voltage at predetermined intervals. Low standby current 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 capacity 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 increase the load current capability.
Should, during the test pulse, the sense terminal voltage fall below the threshold level determined by the internal (synthesized) temperature compensated 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 conjunction with an external RC network, operate as a Òpulse-stretcherÓ to provide 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 maximum permissible output current is 30mA.
