The R5492 is a high voltage tolerance protection IC for overcharge, overdischarge, and overcurrent of a rechargeable one-cell Lithium-ion (Li+) / Lithium-polymer battery. The R5492 supports the voltage release type at overcharging / overdischarging.
Each output delay time of overcharge, overdischarge, and overcurrent is fixed internally. But, the delay shortening is able to shorten the detection and the release delay times at overcharging / overdischarging. Especially, the overcharge detection delay time can be shorten to aprrox.1/90.
