R5462 Series
High Accuracy 2-Cell Li-ion Battery Protection IC
The R5462 Series are high voltage CMOS-based protection ICs for over-charge/discharge of rechargeable two-cell Li-ion/Lithium polymer, further include a short protection 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 detectors, a temperature detector, 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. DFN(PLP)1820-6B package is available.
