Renesas Electronics PTX130W NFC Wireless Charging IC

Renesas Electronics PTX130W NFC Wireless Charging IC is developed alongside data communication for NFC wireless charging applications. The powerful and efficient PTX130W offers improved vital performance parameters such as output power and RX sensitivity (-80dBc).

The Renesas PTX130W NFC Wireless Charging IC allows simple integration and a compact design without the complexity of existing solutions (dual resonating circuits composed of EMC filter and antenna). The device eliminates the EMC filter and matching components. The superior RF performance of PTX130W enables a small antenna design, fast charging, and flexible placement of Poller and Listener antennas.

Features

  • Allows harvesting up to 1W on the NFC WLC Listener
  • No EMC filter requirement due to sinewave output driver and Direct Antenna Connection (DiRAC)
  • Automated power control loop for system efficiency optimization
  • Output power regulation with a 1% step
  • NFC Forum WLC Poller functionalities
  • NFC Data exchange with impedance change detection for FOD
  • On-chip processing of time-critical commands

Applications

  • Universal NFC charger
  • Smart rings
  • Smart glasses
  • Fitness trackers
  • Smartwatches
  • Medical devices
  • Headsets
