R5422N111E - Li-Ion BATTERY PROTECTOR
PRELIMINARY ’99.12.9 Li-Ion BATTERY PROTECTOR R5422NxxxC/xxxE series n OUTLINE The R5422NxxxC/E Series are protection ICs for over-charge/discharge of rechargeable one-cell Lithium-ion (Li+) excess load current, further include a short circuit protector for preventing large external short circuit current.
Each of these ICs is composed of three voltage detectors, a reference unit, a delay circuit, a short circuit protector, and a logic circuit.
When charging voltage crosses the detector thresh
