Overview

MC33340/MC33342 はモノリシック制御 IC で、ニッケル・カドミウム (NiCd) / ニッケル金属水素化物 (NiMH) 電池の高速充電コントローラに特化して設計されています。高速充電終了の主な方法としての負スロープ電圧検知が特長です。正確な検知を確保するのは、電圧サンプリングの精度を上げるために充電電流へ一瞬割り込む出力です。バックアップ終了のセカンダリ・メソッドを追加して、時間と温度制限のいずれかをプログラミング可能にすることもできます。保護機能には、バッテリ過電圧/低電圧検知、過熱検知のラッチ、ヒステリシスによる電源入力低電圧ロックアウトがあります。MC33340 と MC33342 の違いは、高速充電のホールド・オフ時間のみです。MC33340 の標準ホールド・オフ時間は 177 秒、MC33342 の標準ホールド・オフ時間は 708 秒です。

  • Negative Slope Voltage Detection with 4.0 mV Sensitivity

  • Programmable 1 to 4 Hour Fast Charge Time Limit
  • Programmable Over/Under Temperature Detection
  • Battery Over and Undervoltage Fast Charge Protection
  • Power Supply Input Undervoltage Lockout with Hysteresis
  • Operating Voltage Range of 3.25 V to 18 V
  • 177 seconds Fast Change Hold-off Time (MC33340)
  • 708 seconds Fast Change Hold-off Time (MC33342)
