Circuit and method for detecting absent battery condition in a linear charger |
摘要 |
A circuit and method for detecting absent battery condition in a linear charger apply a detecting signal onto an output terminal of the charger and monitor the output terminal to receive a detected signal. The capacitance at the output terminal is significantly different between the presence and absence of a battery connected to the output terminal, and it is thus available to determine from the detected signal, if no battery is connected to the output terminal.
