A typical standby supply current requirement of only 1.6mA allows these ICs to predictably monitor ambient temperatures. \u003cbr\u003eSeparate voltage loop and current limit amplifiers regulate the output voltage and current levels in the charger by controlling the onboard driver. \u003c\/div\u003e\n\u003cdiv class=\"inner\"\u003e\n\u003cbr\u003eThe driver will provide up to 25mA of base drive to an external pass device. Voltage and current sense comparators are used to sense the battery condition and respond with logic inputs to the charge state logic. A charge enable comparator with a trickle bias output can be used to activate a low current turn-on mode of the charger, preventing high current charging during unusual conditions such as a shorted battery cell. \u003c\/div\u003e\n\u003cdiv class=\"inner\"\u003e\n\u003cbr\u003eThe UC3906 also features a supply under-voltage sense circuit with a logic output to indicate when input power is available. In addition the over-charge state of the charger can be externally monitored and terminated using the over-charge indicate output and over-charge terminate input.\u003cbr\u003e \n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul class=\"productfeatures\"\u003e\n\u003cli\u003eOptimum Control for Maximum Battery Capacity and Life\u003c\/li\u003e\n\u003cli\u003eInternal State Logic Provides Three Charge States\u003c\/li\u003e\n\u003cli\u003ePrecision Reference Tracks Battery Requirements Over Temperature\u003c\/li\u003e\n\u003cli\u003eControls Both Voltage and Current at Charger Output\u003c\/li\u003e\n\u003cli\u003eSystem Interface Functions\u003c\/li\u003e\n\u003cli\u003eTypical Standby Supply Current of only 1.6mA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eMore information:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDownload \u003ca title=\"UC3906 datasheet\" rel=\"noopener noreferrer\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2386\/9605\/files\/uc3906.pdf?4910211163994813856\" target=\"_blank\"\u003edatasheet\u003c\/a\u003e (.pdf).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eDon't forget to check out our full range of \u003ca rel=\"noopener\" title=\"Integrated Circuits from PMD Way with free delivery\" href=\"https:\/\/pmdway.com\/collections\/integrated-circuits\" target=\"_blank\"\u003eIntegrated Circuits\u003c\/a\u003e if this doesn't meet your needs.
