アナログ・デバイセズの電源管理ICは、確実なバッテリー管理によって製品の信頼性を向上させ、最終製品のバッテリー寿命を延長します。
電源管理ICの代表的な製品としてはADP5065やADM706などがあります。
ADP5065は2011年にリリースされた新製品で、USB3.0とUSB2.0に対応した1セルLi電池向けスイッチング・バッテリー充電ICです。4V~5.5Vの入力電圧範囲に対応しており、20Vまでの電圧耐性を持っています。デジタルカメラやデジタルビデオカメラ、また携帯電話などの用途に最適です。スイッチングタイプのチャージャーですので、入力電流が500mAで制限されても、それ以上の充電電流が狙えるため、従来のリニアチャージャーよりも急速に充電することが狙えます。I2Cによるデジタル制御により、細かい充電制御を可能にし、JEITAに準拠した電池温度に合わた充電電流を制御することができます。
また、アナログ・デバイセズではバッテリ異常時を検出するため電圧管理ICを多数取り揃えています。中でもADM706は、3Vまたは3.3Vのバッテリー管理に適したICです。マイクロプロセッサ・システムや各種コントローラなどの用途に適しています。また、ADM706は日本法人のおススメ製品として選出されており、優れたパフォーマンスと豊富な採用実績を持っています。おススメ選定製品郡は優先的な技術サポートも保証されていますので、是非ご検討ください。
