What is a Wireless Charging IC?

Wireless charging ICs operate by utilizing the principle of electromagnetic induction to transfer energy wirelessly from a transmitter to a receiver. The transmitter employs an induction coil to generate an alternating electromagnetic field, which the receiver coil converts back into electricity and feeds into the battery of the device. This process is also referred to as inductance coupling or magnetic coupling.

The wireless charging ICs are ideal for use in smartphones, tablets, Portable Medical Devices, Power tools, Notebooks, Tablets, Water or dustproof portable devices, smart home, IoT devices, Smart Watches, Wearables, Toys, Portable Lighting, and Medical Devices.

Key features of Wireless Charging ICs:

• Overvoltage protection.
• Under-voltage protection.
• Short circuit protection.
• Over-temperature protection.
• Offering a high level of programmability.
• Detection of a foreign metal object to prevent undesirable heating.
• Consume low standby power.
• Facility to indicate operating mode and fault mode.

Key Specifications of Wireless Charging ICs:
