R5470x/R5471x series is a high input voltage CMOS-based protection IC for over-charge/discharge and over-current of rechargeable one-cell Lithium-ion/Lithium polymer battery. They can detect over-charge/discharge and excess-current of one-cell Li-ion, further include a short circuit protection. They consist of four voltage detectors, reference units, a delay circuit, a short circuit detector, an oscillator, a counter, and a logic circuit. Voltage accuracy is superior to previous items. DFN(PLP)2114-4B (for R5470K) and DFN(PLP)1616-6B (for R5471K) packages are available.
The R5470x/5471x Series are high input voltage CMOS-based protection integrated circuits designed for over-charge, over-discharge, and over-current protection of rechargeable one-cell Lithium-ion (Li-ion) and Lithium polymer (Li-polymer) batteries. These ICs include short circuit protection and consist of four voltage detectors, reference units, a delay circuit, a short circuit detector, an oscillator, a counter, and a logic circuit.
