Abstract
【解決手段】電圧レギュレータ6からの電圧レギュレータ7への電流の供給通路LAに電流制御素子(可変抵抗素子)12を設ける。電圧レギュレータ6からの電圧レギュレータ7への電流の分流通路LBにアラーム駆動回路8を設ける。アラーム駆動回路8を作動させる必要がある場合、電流制御素子制御部3−3は、電流制御素子12の抵抗値を制御し、供給通路LBを流れている電流IAを分流通路LBに分流させる。この際、分流通路LBへ分流する電流IBは、アラーム駆動回路8の動作に必要な量とする。この場合、電圧レギュレータ7には電流IAとIBとの合流電流が供給され、アラーム駆動回路8を作動させる前と同じであるので、CPU3への供給電力が不足することはない。
【選択図】 図1
Description
副次的な機能を働かせる必要がない場合、すなわちアラーム駆動回路8を作動させる必要がない場合、電流制御素子制御部3−3は、電流制御素子12の抵抗値を0とする。これにより、供給通路LAを流れている電流IAは、分流通路LBに分流されずに、電圧レギュレータ7に送られる。ここで、分流通路LBを流れる電流をIBとすると、IB=0とされる。
副次的な機能を働かせる必要がある場合、すなわちアラーム駆動回路8を作動させる必要がある場合、電流制御素子制御部3−3は、電流制御素子12の抵抗値を制御し、供給通路LBを流れている電流を分流通路LBに分流させる。この際、分流通路LBへ分流する電流IBは、アラーム駆動回路8の動作に必要な量とする。
