R5617 SeriesNEW

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

  • RoHS

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.

  • 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
