A system comprising a supply voltage isolation module ( ), and a battery detector ( ), both responsive to a battery pin ( ). The system further including a voltage detection module ( ) responsive to a voltage supply pin ( ), where the voltage detection module ( ) compares a supply voltage from the voltage supply pin ( ) to a threshold. The system also including control logic ( ) responsive to the battery detector ( ) and the voltage detection module ( ). Also disclosed are methods for responding to connection of a battery ( ) to a logic device ( ), placing a logic device ( ) into a low power state in response to connection of a battery ( ) to the logic device ( ), and detecting a battery condition for a logic device ( ) having a battery pin ( ).
