The R5402N101KD can detect over-charge/discharge of Li+ one-cell and excess load current, further include a short circuit protector for preventing large external short circuit current and the excess charge-current. The R5402N101KD consists of four voltage detectors, a reference unit, a delay circuit, a short circuit detector, an oscillator, a counter, and a logic circuit. When the R5402N101KD detects over-charge or over-charge current, the output of COUT pin switches to “L” level, that is, the charger’s negative pin level after the internal fixed delay time. When the R5402N101KD detects over-discharge or excess discharge current, the output of DOUT pin switches to “L” level after the internal fixed delay time. After detecting over-charge voltage or over-charge current, if the battery voltage is lower than over-charge www.DataSheet4U.com detector threshold voltage, the R5402N101KD can be reset and the output of COUT becomes “H” when a kind of load is conne...
