1-Cell Li-ion Battery Protection IC

The Nisshinbo Micro Devices Overcharge Protection IC is used 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 RSENS 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.

Absolute maximum rating is 30 V
Supply current on normal mode is Typ. 4.0 μA
