Abstract
A temperature sensor adapted in a charge and discharge control circuit of a secondary battery, cooperates with a micro-controller of the charge and discharge control circuit. The temperature sensor is a non-polar temperature sensor manufactured by the semiconductor manufacturing technology. The temperature sensor includes a first signal pin, a second signal pin, a first thermal diode, and a second thermal diode paired with the first thermal diode. The positive electrode of the first thermal diode and the negative electrode of the second thermal diode, both connect to the first signal pin. The negative electrode of the first thermal diode and the positive electrode of the second thermal diode, both connect to the second signal pin. The temperature sensor is proofread easily, has a low manufacturing cost, consumes less power and has an excellent anti-interfere capability, etc.
