Key Products
In a wireless battery charging system, power is transferred by electromagnetic induction between a transmitter (Tx) pad, or dongle, and a receiver (Rx) device. Single- or multiple-coil wireless chargers are finding widespread use in many locations, including airports, cafes, supermarkets, and factories. The advantages of wireless chargers include greater spatial freedom, they are fully impervious to water and dust, and can even be contactless. Popular wireless charging applications include smart phones and watches, robot cleaners, and other industrial tools.

Key challenges

  • Power and efficiency levels to compete with wired power transfer.
  • Stable performance in the presence of foreign objects or when transmitters or receivers are moved.
  • High safety for humans and other nearby devices.
  • The ability of different Tx and Rx products to work together freely.
  • High integration for compact and cost-effective designs with fast time-to-market.
