The R5617x 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
● Supply Current:
Normal mode: Typ. 2 µA / Max. 4 µA
Standby mode: Max.0.2 µA (V
DET2
: Auto Release type) / Max.0.04 µA (V
DET2
: Latch type)
