<p><P>PROBLEM TO BE SOLVED: To stably reset a microcomputer inside a battery pack without upsizing the battery pack. <P>SOLUTION: This battery pack 1 having a secondary battery 2, and an arithmetic circuit 4 connected to the secondary battery 2, calculating and outputting a state of the secondary battery 2 has: a connection terminal T<SB>D</SB>connected to an internal terminal T<SB>ID</SB>of the arithmetic circuit 4, for outputting an arithmetic result to the outside; a voltage decision part 5a connected to the connection terminal T<SB>D</SB>, outputting an internal voltage signal V<SB>log</SB>wherein an external voltage signal V<SB>D</SB>applied to the connection terminal T<SB>D</SB>is compared with a prescribed threshold voltage V<SB>r1</SB>; an integration circuit 5b integrating the internal voltage signal V<SB>log</SB>to generate an internal voltage signal V<SB>C</SB>; and a voltage decision part 5c receiving the internal voltage signal V<SB>C</SB>, comparing the internal voltage signal V<SB>C</SB>and a prescribed threshold voltage V<SB>r2</SB>to generate an internal reset signal V<SB>R</SB>, and inputting the internal reset signal V<SB>R</SB>to an internal terminal T<SB>IR</SB>of the arithmetic circuit 4. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
