Abstract
An apparatus and method for diagnosing a watchdog timer is provided. The watchdog timer is used to detect and recover from a malfunction of a battery management system. Before entering a shutdown mode in response to a shutdown command from an external device, the apparatus outputs an invalid trigger signal to the watchdog timer and diagnoses a malfunction of the watchdog timer depending on whether the watchdog timer outputs a reset signal.
