PROBLEM TO BE SOLVED: To provide a power supply distribution device and a power supply distribution system capable of suppressing manufacturing cost, and which are used in a vehicle that adopts a multivoltage method.SOLUTION: In a power supply distribution device 20, a semiconductor switch 31 that is an N-channel field-effect transistor included in each of a plurality of circuit sections 30 is provided between a first power supply section 11 and each of a plurality of loads L. A second voltage V2 output from a second power supply section 12 is a voltage that is higher than a first voltage V1 output from the first power supply section 11 and that can control a plurality of semiconductor switches 31 to be turned on. A control signal for instructing an ON/OFF control over the semiconductor switches 31 is input to a control unit 40. A power supply control circuit 33 connects a gate terminal G of the semiconductor switch 31 to be controlled to be turned on to the second power supply section 12 and disconnects the gate terminal G of the semiconductor switch 31 to be controlled to be turned off from the second power supply section 12, in response to the control signal.

    【課題】多電圧化を採用した車両において用いられる製造コストを抑えた電源分配装置及び電源分配システムを提供する。【解決手段】電源分配装置20は、複数の回路部30がそれぞれ有するNチャンネル型の電界効果トランジスタである半導体スイッチ31が、第1電源部11と複数の負荷Lとの間にそれぞれ設けられている。第2電源部12が出力する第2電圧V2が、第1電源部11が出力する第1電圧V1より高い電圧でかつ複数の半導体スイッチ31をオン制御可能な電圧とされている。制御部40には、複数の半導体スイッチ31についてオン/オフ制御を指示する制御信号が入力される。そして、電源供給制御回路33が、上記制御信号によってオン制御の半導体スイッチ31のゲート端子Gと第2電源部12を接続し、かつ、オフ制御の半導体スイッチ31のゲート端子Gと第2電源部12とを遮断する。【選択図】図2
