Abstract

A secondary battery protection apparatus includes a temperature sensitive element and a secondary battery protection circuit with a first terminal coupled to an external device and the temperature sensitive element to control charge and discharge using a switching circuit to protect a secondary battery from temperature, and a conversion circuit of the secondary battery protection circuit is controlled such that a first input of a comparison circuit to compare a voltage against a threshold is electrically coupled to the first terminal of the secondary battery protection circuit, the voltage corresponding to a change in temperature of the secondary battery.
