1. A semiconductor device comprising:
a wired connection;
a wireless connection;
a battery;
a wired charging path between the wired connection and the battery comprising:
a first transistor; and
a second transistor;
a wireless charging path between the wireless connection and the battery comprising:
a third transistor; and
the second transistor;
a charger controller that is configured to control an activation of the second transistor; and
a charging detector circuit that is configured to:
detect current between the third transistor and the battery; and
transmit a signal to the charger controller based at least in part on current between the third transistor and the battery to control an activation of the second transistor.
