The utility model relates to a novel excess temperature protection circuit, including being used for detecting the temperature detecting element of battery temperature, still include through the low -temperature protection unit is crossed in charge -discharge that temperature detecting element coupled together and the high temperature protection unit is crossed in the charge -discharge, wherein, temperature detecting element crosses the input?ports?are?connected that the high temperature protection unit was crossed in low -temperature protection unit and charge -discharge with the charge -discharge respectively, the port OTP that output port that low -temperature protection unit and charge -discharge crossed the high temperature protection unit all was connected to the battery is crossed in the charge -discharge. Compared with the prior art, the utility model discloses only use 2 operational amplifier, effectively reduce the use amount of components and parts for circuit structure is simple, easily realizes,
