Abstract
【解決手段】自動復帰回路の出力と二次電池の電圧を比較し、自動復帰回路の出力が大きい時、つまり外部端子間に充電器が接続された時のみ温度センサ回路を動作させる。
【選択図】図1
Description
本実施形態のバッテリ装置は、二次電池101と、放電制御用PchFET102と、充電制御用PchFET103と、負荷104または充電器105が接続される外部端子106及び107と、抵抗108と、自動復帰回路111と、コンパレータ112と、温度センサ回路113と、充放電制御回路114と、0V充電制御回路115と、NMOSトランジスタ116とダイオード117とを備えている。
外部端子106と107の間に重負荷が接続されると、充放電制御回路114が過電流を検出して、過電流保護機能が動作して放電制御用PchFET102をオフさせる。過電流検出端子123の電圧は0V近辺まで低下する。自動復帰回路111は、重負荷が取り除かれた時の自動復帰に備えて動作し、過電流検出端子123に電流を流す。その後、重負荷が取り除かれると過電流検出端子123の電圧は徐々に上昇していく。この時、コンパレータ112には非反転入力端子に正のわずかなオフセットをもたせてあるため、出力はLレベルの信号を出力し温度センサ回路113の回路動作を止めている。そして、充放電制御回路114は重負荷が取り除かれたことを検知して放電制御用PchFET102をオンさせる。こうして過電流検出端子123の電圧は二次電池101の正極と同じ電圧になる。
