  • Methods and systems for detecting and for responding to connection of a battery to a logic device
    Patent number: 6487670
    Abstract: A system comprising a supply voltage isolation module (50), and a battery detector (52), both responsive to a battery pin (41). The system further including a voltage detection module (54) responsive to a voltage supply pin (42), where the voltage detection module (54) compares a supply voltage from the voltage supply pin (42) to a threshold. The system also including control logic (56) responsive to the battery detector (52) and the voltage detection module (54). Also disclosed are methods for responding to connection of a battery (36) to a logic device (12), placing a logic device (12) into a low power state in response to connection of a battery (36) to the logic device (12), and detecting a battery condition for a logic device (12) having a battery pin (41).
