Abstract:
A semiconductor integrated circuit may include a recharge switch and a Wireless Recharge/MST unit. The recharge switch is connected with a battery through an intermediate node and provides a current path for wirely charging the battery in a wired charging mode. The Wireless Recharge/MST unit is connected between the intermediate node and a ground. The Wireless Recharge/MST unit disconnects the intermediate node and the ground in the wired charging mode, provides a wireless charging current to the battery through the intermediate node in a wireless charging mode, and is supplied with a current for generating a magnetic signal from the battery through the intermediate node in a magnetic secure transmission (MST) mode.
