1. An aerosol generating device comprising:
a heater configured to heat an aerosol generating material to generate an aerosol;
a battery configured to supply power to the heater;
a controller;
a first circuit unit separately provided from the controller and configured to control operation of the heater; and
a second circuit unit configured to control charging and discharging of the battery, wherein the controller is configured to:
determine an operating state of the aerosol generating device as one from among a heating state and a non-heating state,
based on determining the operating state as the heating state, receive first data about an amount of first current flowing through the first circuit unit, and determine an abnormality in the first circuit unit based on the first data about the amount of the first current, and
based on determining the operating state as the non-heating state, receive second data about an amount of second current flowing through the second circuit unit, and determine an abnormality in the second circuit unit based on the second data about the amount of the second current.
