1-cell Li-ion Battery Protection IC with High-accuracy Overcurrent Detection and Selectable RESET Function

Download Datasheet

  • Description

    The R5613 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 and the RST pin function which can switch for an external MOSFET to either a RESET or a forced-standby state.

    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
    • Switching to RESET or Forced-standby State by RST Pin: Allowed External Control of Load
