R5612 One-Cell Li-ion/ Polymer Battery Protection IC

Ricoh Electronic Devices has introduced the R5612 Series of a one-cell Li-ion/ polymer battery protection IC for providing overcharge, over-discharge, and charge/discharge overcurrent detections. The new device can offer a supply current of 2.5- 4.8µA in normal mode and up to 0.2-0.4 µA in standby mode. The R5612 series comes with charge/discharge overcurrent detectors with high accuracy of ±1.0 mV.

Along with a low voltage and high accuracy, the R5612 series also offers lower resistance of sense resistor by overcurrent detector. This helps in providing onboard heat reduction. The device achieves a longer driving time with a battery of small capacity by consuming a low current and with a low standby current. The low current consumption makes the R5612 series ideal for smartphones, tablet PC, gaming consoles, and hearing aids.
