CHARGING CONNECTOR OVERHEAT DETECTION AND PROTECTION APPARATUS

摘要

The present invention provides an apparatus that includes a resistive control block (RCB) coupled to data lines of a universal serial bus (USB) connector charging port and is configured to change a level of resistance between the data lines. The apparatus further includes a sensing and adjustment block (SAB) that is configured to sense a predetermined level of overheating of the USB connector charging port and cause the RCB to increase the level of resistance resulting in the USB connector charging port to appear as a different type of port. In another embodiment, an apparatus includes a RCB and SAB. The RCB is coupled to an identification and ground lines of a USB connector and configured to change a level of resistance between them. The SAB is configured to sense a predetermine level of overheating of a USB connector and cause the RCB to decrease the level of resistance.

1. An apparatus comprising:
a resistive control block, coupled to a first data line and a second data line of a universal serial bus connector charging port, configured to change a level of resistance between said first data line and said second data line; and a sensing and adjustment block, coupled to said universal serial bus connector charging port, configured to sense a predetermined level of overheating of said universal serial bus connector charging port and cause said resistive control block to increase said level of resistance resulting in said universal serial bus connector charging port to appear as a different type of port.
