SEMICONDUCTOR DEVICE FOR MONITORING BATTERY REMAINING CAPACITY

A semiconductor device capable of reducing errors in sensing a remaining amount of a battery even when a temperature of the battery varies is provided. The semiconductor device for monitoring a battery state includes a prediction unit (13_1) that predicts a temperature at a time of discharge termination of the battery according to a temperature of the battery at a predetermined time and outputs a voltage of the battery in consideration of the predicted temperature at the time of the discharge termination, and a remaining amount detecting unit (13_2) that detects the remaining amount of the battery based on the voltage of the battery outputted by the prediction unit and a current of the battery at a predetermined time.
