Key features

  • Qi Wireless Charging
    • Qi standard compliance ensures a consistent, safe, and simple user experience with other Qi certified products
  • Foreign Object Detection (FOD)
    • FOD provides detection accuracy and helps avoid overheating during charging
  • Spatial Freedom
    • Proprietary adaptive rectifier configuration (ARC) mode enhances the detection distance by up to 50% in all directions
  • Fast Charging
    • Extended power profile (EPP) speeds up charging time by up to three times
  • High Efficiency
    • Excellent energy efficiency with built-in power management
  • Protection Features
    • Protections include on-chip thermal management, and overvoltage and overcurrent protection to prevent overheating
  • Reverse Charging Mode
    • Receivers can operate as a wireless transmitter without any change in hardware design
  • Sustainable Solution
    • Charging sockets take space and allow water and dust to enter devices; eliminating them therefore extends product life
  • Reduced BOM Count
    • Simplifying wireless power transmitter systems with less discrete components.
  • Communication interfaces
    • Inbuilt I²C, UART, SPI, and GPIO interfaces simplify parameter configuration.

Longevity Commitment

Most of ST’s wireless power ICs come with our 7-year longevity commitment.





15W Qi-Compliant Wireless Power Receiver Solution

An integrated Wireless Power Receiver, the STWLC38 is designed to support Qi 1.3 specifications for inductive communication protocols supporting the 5W Baseline Power Profile and 15W Extended Power Profile.
