データシート
型番 説明 主な特長
MAX16072, MAX16073, MAX16074 4ピン(1mm x 1mm)チップスケールパッケージ、µP監視回路

小型パッケージがスペースを節約し、低電力動作がバッテリ寿命を延長
MAX16056, MAX16057, MAX16058,
...		 コンデンサ可変のリセットおよびウォッチドッグタイムアウト内蔵、125nA監視回路

電力およびバッテリ寿命を節約。複数アプリケーションにわたって可変タイムアウトで1つのICを使用。
MAX16060, MAX16061, MAX16062 精度1%、クワッド/ヘックス(6回路)/オクタル(8回路)電圧µP監視回路

幅広い特長およびオプションが多くの設計ニーズに応える柔軟性を提供
MAX6443, MAX6444, MAX6445,
...		 長いマニュアルリセットセットアップ時間を備えた、µPリセット回路

高精度電圧監視によって短時間のスイッチ動作(厄介なリセット)を回避。フロントパネルスイッチ接続の組み合わせで機器の筐体のリセット穴が不要。
MAX6746, MAX6747, MAX6748,
...		 コンデンサ可変リセット/ウォッチドッグタイムアウト遅延内蔵、µPリセット回路

使い易い高集積ソリューションでスペースを節約し設計を簡素化
