Abstract
It is possible to limit the use of non-authentic battery packs. A battery control IC (200) includes an authentication circuit (208) and a charge/discharge control circuit (210). The charge/discharge control circuit (210) controls charging and discharging of a battery (22). The authentication circuit (208) performs a process for performing an authentication with a host device. The authentication circuit (208) is configured to perform a process associated with a first authentication in a common key system. The charge/discharge control circuit (210) is configured to perform a control to enable a discharge operation when the first authentication is established.
