Abstract
A battery protection circuit with quickly testable design is disclosed. According to one embodiment, the battery protection circuit includes a battery voltage detection circuit configured to detect a battery voltage, output an effective trigger signal if the battery voltage reaches a voltage protection threshold, and output an ineffective trigger signal otherwise; a delay circuit configured to receive the trigger signal, output an effective status signal if the trigger signal is maintained effective continuously over a period of time, and outputs an ineffective status signal otherwise; a protection driver configured to receive the trigger signal and the status signal, enter a driving state when both the trigger signal and the status signal are effective, enter a non-driving state when both the trigger signal and the status signal are ineffective, and enter a ready driving state when the trigger signal is effective and the status signal is ineffective.
