FUEL GAUGE CIRCUIT AND BATTERY PACK
First Claim
1. A fuel gauge circuit which detects a residual quantity of a battery and is disposed on a substrate together with a protection circuit which protects charging and discharging of the battery, the fuel gauge circuit comprising:
- a voltage monitor terminal disposed on a side of the fuel gauge circuit, facing a positive power-supply terminal of the substrate, and connected to each of the positive power-supply terminal of the substrate and a voltage sensor disposed in the fuel gauge circuit;
a voltage through terminal disposed on a side of the fuel gauge circuit, facing the protection circuit and being opposite to the side facing the positive power-supply terminal, and connected to a voltage monitor terminal of the protection circuit; and
a wiring disposed within the fuel gauge circuit to connect the voltage monitor terminal of the fuel gauge circuit to the voltage through terminal.

Abstract
A fuel gauge circuit detects a residual quantity of a battery 1 and is disposed on a substrate 20 together with a protection circuit 40 which protects charging/discharging of the battery 1. The fuel gauge circuit includes a voltage monitor terminal T1 disposed on a side facing a positive power-supply terminal 21 of the substrate and connected to each of the positive power-supply terminal 21 and a voltage sensor 31 disposed in the circuit, a voltage through terminal T6 disposed on a side facing the protection circuit, opposite to the side facing the positive power-supply terminal 21, and connected to a voltage monitor terminal T11 of the protection circuit, and a wiring 32 disposed within the circuit to connect the voltage monitor terminal T1 of the fuel gauge circuit to the voltage through terminal T11.
