摘要 |
A method for detecting removal of a battery from a battery charger includes 1) incrementing an event counter and resetting an interval counter each time the voltage present at the output node exceeds a predetermined voltage; 2) resetting the event counter each time the interval counter exceeds a predetermined maximum time between events; and 3) asserting a signal indicating the absence of a battery connected between the positive and negative output nodes each time event counter exceeds a predetermined number of events.
