The R5460x Series are high voltage CMOS-based protection ICs for over-charge/discharge of rechargeable two-cell Li-ion/Lithium polymer. They include a short circuit protection circuit for preventing large external short circuit current and protection circuits against excess discharge-current and excess charge current. Each IC consists of six voltage detectors, reference units, a delay circuit, a short circuit protector, an oscillator, a counter, and a logic circuit. In addition to SOT-23-6 package, DFN(PLP)1820-6 package is also available.
