R5400N Series
Li-ion/polymer 1Cell Protector
The R5400N Series are high input voltage CMOS-based protection ICs for over-charge/discharge of rechargeable one-cell Lithium-ion
(Li-ion) / Lithium polymer excess load current, further include a short circuit protector for preventing large external short circuit
current and excess discharge-current.
Each of these ICs is composed of three voltage detectors, reference units, a delay circuit, a short circuit detector, an oscillator, a
counter, and a logic circuit. SOT-23-5 package is available.
