Li-ion protectionLi-polymer protectionsingle cellintegrated MOSFETDFN2x2-6battery pack protection

XB6166IS is a compact one-cell Li-ion/Li-polymer protection IC with integrated MOSFETs for small battery packs.

Best for

  • Compact 1-cell Li-ion battery packs
  • 1-cell Li-polymer battery packs
  • Portable low-power electronics

Avoid if

  • Multi-cell battery packs
  • Designs requiring a confirmed lifecycle or MSL classification
  • Applications exceeding the IC thermal or current limits

Check before use

  • Cell charging voltage versus 4.30 V typical overcharge detection
  • Cell undervoltage requirement versus 2.80 V typical overdischarge detection
  • Load peak current and short-circuit behavior
  • Thermal rise from integrated 45 mΩ typical FET resistance
