Wireless chargers are expected to become ubiquitous in hotels, airports, cafes and other public places as they enable to top up the batteries of portable and wearable devices, letting the user forget about cables.
In a Wireless battery charging system, power is transferred by electromagnetic induction between a transmitting pad - or dongle (TX) - and the battery-powered device (RX), such as a smartphone, smartwatch or sports gear. The power transmitter unit controls the current in the transmitting coil to transfer the correct amount of power as required by the receiver unit that continuously provides this information to the transmitter by modulating the transmitter carrier frequency through controlled resistive or capacitive load insertion. Generating the correct amount of power guarantees the highest level of end-to-end energy efficiency and helps limit the device’s operating temperature.
We have a range of wireless battery charging solutions including transmitters and receivers providing low stand-by power and features like foreign objects detection (FOD) as well as evaluation and development tools and reference design to help develop high-efficiency and compact chargers compliant with the most common wireless charging standards including Qi and AirFuel.
