Abstract
An apparatus for providing a connection to a wide area network for voice calls includes a wide area network circuit configured to transmit voice call data packets, a phone connection circuit configured to receive a voice call signal from a phone, a processor circuit configured to generate voice call data packets based on a voice call signal received by the phone connection circuit and a power management circuit configured to switch off at least a part of the apparatus to reach a power down mode of the apparatus, if a supply voltage drops below a supply voltage threshold.
Claims8
A power management circuit comprising:
- at least one switch;
- a switch control unit configured to control the at least one switch;
- a battery contact interface for connecting the power management circuit to a battery;
- a phone contact interface for connecting the power management circuit to a phone connection circuit;
- a processor contact interface for connecting the power management circuit to a processor circuit;
- wherein the switch control unit is configured to control the at least one switch to connect the processor contact interface to the battery contact interface if a current through the phone contact interface increases beyond a current threshold.
