A pair of 50-W Qi-compatible improvement boards from ST allows speedy wi-fi charging utilizing the corporate’s ST Tremendous Cost (STSC) protocol. The STEVAL-WBC2TX50 transmitter and STEVAL-WLC98RX receiver boards speed up the event of wi-fi charging for merchandise starting from medical and industrial gear to house home equipment and laptop peripherals.
By using the STSC protocol, the transmitter board delivers as much as 50 W of output energy at a quicker wi-fi charging charge than normal protocols used with smartphones and related units. The board additionally helps the Qi 1.3 5-W Baseline Energy Profile (BPP) and 15-W Prolonged Energy Profile (EPP) specs. Onboard elements embody an Arm Cortex-M0-based transmitter system-in-package, application-specific entrance finish, and MOSFET gate drivers. ST’s STSAFE-A110 safe component supplies QI authentication.
Just like the transmitter board, the receiver board additionally gives as much as 50 W of charging energy, full STSC functionality, and BPP/EPP charging. Its adaptive rectifier configuration (ARC) mode extends charging distance by as much as 50% to permit lower-cost coils and configuration flexibility. The board’s wi-fi energy receiver IC, based mostly on an Arm Cortex-M3 processor, includes a synchronous rectifier energy stage that gives a programmable output voltage as much as 20 V.
Costs for the STEVAL-WBC2TX50 transmitter and STEVAL-WLC98RX receiver begin at $109.03 and $113.93, respectively. Each boards can be found from the ST eStore.
