Wireless Charging Transmitter by STMicroelectronics (3 more products)

Note : Your request will be directed to STMicroelectronics.

The STWBC-EP from STMicroelectronics is the digital controller for the wireless battery charger transmitters specifically designed to support the WPC 1.2 EPP (Extended Power Profile) applications up to 15 W. This transmitter is responsible for controlling the transmitting coil and generating the correct amount of power requested by the RX. The RX continuously provides the transmitter with the correct power level requested, by modulating the transmitter carrier through the controlled resistive or capacitive load. It can adapt to the amount of energy transferred by the coil by modulating the frequency, duty cycle or amplitude of the PWM voltage on the transmitting coil. It also helps maintaining a lower operational temperature. The STWBC-EP is capable of bidirectional communication with the RX as specified by the WPC 1.2 protocol.

The STWBC-MC is available in a 5 x 5 mm VFQFPN32 package and is ideal for smartphones, tablets and other battery-powered devices that use the electromagnetic induction for recharging.
