R5612 Series
1-cell Li-ion Battery Protection IC with High-accuracy Overcurrent Detection
-
Description
The R5612 Series 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 ±1.0 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
