R5617x Series
One
-cell Li-ion Battery Protection IC with High-accuracy Overcurrent Detection
No.EA-604-230601
1
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)
● Detector Selectable Range and Accuracy

When selecting each set voltage of V
DET31
, V
DET32
and V
SHORT1
, keep from overlapping among them in consideration of
their voltage accuracy. Especially, it is required that V
SHORT1
be 7.5 mV higher than V
DET31
and V
DET32
.
