POWER SUPPLY UNIT FOR AEROSOL GENERATING DEVICE, METHOD FOR CONTROLLING POWER SUPPLY UNIT FOR AEROSOL GENERATING DEVICE, AND PROGRAM FOR POWER SUPPLY UNIT FOR AEROROSOL GENERATING DEVICE

摘要

PROBLEM TO BE SOLVED: To detect occurrence of a defect in a sensor. A power supply unit (300) detects a change in electric current of a microphone capacitor (331) that detects an aerosol generation request, and a PTC based on an electric change of the microphone capacitor (331), and outputs a value based on the change. A thermistor 332 and a control unit 340 that detects whether the state of the microphone capacitor 331 is the normal state or the non-normal state based on the value output from the PTC thermistor 332.
