摘要： A secondary battery protection circuit for protecting a secondary battery including: a power supply terminal; a protection operation circuit configured to monitor a state of the secondary battery through the power supply terminal to generate a signal for turning on/off conduction of a current path between the secondary battery and a load according to a protection state determined by the monitored state of the secondary battery; a nonvolatile memory in which data is written by a writing voltage being provided at the power supply terminal, an operation of the secondary battery protection circuit being controlled by the data; a voltage generation circuit configured to generate a provision voltage which is provided to a low withstand voltage circuit; and a control circuit configured to enable the nonvolatile memory to store the data therein in accordance with the protection state upon an input voltage being greater than a determination threshold voltage.
