R5617 Series
One-cell Li-ion Battery Protection IC with High-accuracy Overcurrent Detection

Download Datasheet

  • Description

    The R5617 is a one-cell Li- ion / polymer battery protection IC providing overcharge, overdischarge and charge / discharge overcurrent detections. Major features of this device include charge / discharge overcurrent detectors with high accuracy of ±0.75 mV.

    Key Benefits

    • Lower-resistance of sense resistor by overcurrent detector with lower-voltage and high-accuracy: Achieving heat reduction on board

    • Low consumption current and low standby current: achieving longer driving time with a battery of small capacity
