Wireless Charging ICs are semiconductor devices designed to facilitate wireless transfer of power between a charging pad (transmitter) and devices such as smartphones, tablets, and wearables (receiver) without the need for physical connectors or cables. They play a vital role in the operation of wireless charging systems by managing power conversion, communication, and safety features. These ICs are widely used in consumer electronics, automotive systems, healthcare devices, industrial tools, and public infrastructure. In this article, everything PE has listed some interesting Wireless Charging ICs that were trending on the website in 2024.
