Product Specifications

The R5486 is an overcharge protection IC for Lithium-ion (Li+)/Lithium polymer secondary battery. This device can detect over-charge, over-discharge, excess discharge and excess charge current of one-cell Li-ion (Li+)/Li-ion polymer battery.
The external resistor added to the RSENSE pin can enhance a high precision overcurrent detection. The excess discharge current detection has two stages of detections to ensure the detection accuracy.
The current consumption after the over-discharge detection is suppressed by stopping the internal circuits.
