Nisshinbo R5613L 1-cell Li-ion Battery Protection IC

Nisshinbo R5613L 1-cell Li-ion Battery Protection IC offers overcharge, over-discharge, and charge-/discharge-overcurrent detections. This IC exhibits low consumption current and low standby current to achieve longer driving time with a small capacity battery. The R5613L battery protection IC is capable of charge-/discharge-overcurrent detectors with high accuracy of ±1.0mV. The RST pin function can be switched to either a RESET or a forced standby state for an external MOSFET. Typical applications include smartphones, tablet PCs, games, and hearing aids.

Features

  • Low consumption current and low standby current:
    • Achieves longer driving time with a battery of small capacity
  • Switching to RESET or forced-standby state by RST Pin:
    • Allowed external control of load
  • Lower-resistance of sense resistor by overcurrent detector with lower voltage and high accuracy:
    • Achieves heat reduction on board
