The R5462x Series are high voltage CMOS-based protection ICs for over-charge/discharge of rechargeable two-cell Li-ion/Lithium polymer, further include a short circuit protection circuit for preventing large external short circuit current and the protection circuits against the excess discharge-current and excess charge current. Each of these ICs is composed of six voltage detectors, reference units, a delay circuit, a short circuit protector, an oscillator, a counter, and logic circuits. The over-charge detector threshold is high accuracy such as ±10mV(0°C∼50°C). DFN(PLP)1820-6B package is available.
The R5462K Series are high voltage CMOS-based protection ICs designed for over-charge and over-discharge protection of rechargeable two-cell Li-ion and Lithium polymer batteries. These devices also include short circuit protection circuits to prevent large external short circuit currents, as well as protection against excess discharge and charge currents. Each IC is composed of six voltage detectors, reference units, a delay circuit, a short circuit protector, an oscillator, a counter, and logic circuits.
