Abstract:
(EN) In the present invention, the traffic and processing load of an external circuit of a power management integrated circuit are reduced. A power management integrated circuit comprises a state determination unit and a remaining-battery-power measuring unit. The state determination unit of the power management integration circuit determines whether the battery charge-discharge state corresponds to any of multiple states that are each associated with a different cycle. Moreover, the remaining-battery-power measuring unit of the power management integrated circuit measures the remaining-battery-power each time a cycle ends, the cycle corresponding to the battery charge-discharge state as determined by the state determination unit.
(FR) Selon la présente invention, le trafic et la charge de traitement d'un circuit externe d'un circuit intégré de gestion de puissance sont réduits. Un circuit intégré de gestion de puissance comprend une unité de détermination d'état et une unité de mesure de puissance restante de batterie. L'unité de détermination d'état du circuit intégré de gestion de puissance détermine si l'état de charge-décharge de batterie correspond à l'un quelconque de multiples états qui sont associés individuellement à un cycle différent. De plus, l'unité de mesure de puissance restante de batterie du circuit intégré de gestion de puissance mesure la puissance restante de batterie à chaque fois qu'un cycle se termine, le cycle correspondant à l'état de charge-décharge de batterie tel que déterminé par l'unité de détermination d'état.
(JA) 電源管理集積回路の外部の回路の通信量および処理負荷を削減する。 電源管理集積回路は、状態判定部および電池残量測定部を具備する。この電源管理集積回路において、状態判定部は、互いに異なる周期が対応付けられた複数の状態のいずれに電池の充放電状態が該当するかを判定する。また、電源管理集積回路において、電池残量測定部は、電池の充放電状態のうち、状態判定部によって判定された状態に応じた周期が経過するたびに電池の電池残量を測定する。
