パワーマネジメント

低電力マイコンと高性能アナログ・フロント・エンド(AFE)をワンパッケージに収めたルネサスの電池管理ICは、バッテリの状態を常に監視し、インテリジェントなバッテリシステムを実現します。

多重のフェイルセーフ機能で安全安心をご提供

  • マイコンおよびAFEの自己診断機能内蔵
  • 倉庫保管時等の低消費電力モードでも安全を提供
  • 保護機能内蔵(充電/放電過電流保護、過充電/過放電保護、高温/低温保護)

いかなる環境下でも 高精度な残量検知が可能

  • 電流、電圧、温度検出に特化した高精度ΔΣA/Dコンバータ
  • 電池劣化を考慮した電池残量の算出が可能
