Overview
Description
The PTX30W is a powerful and efficient NFC Listener system-on-chip for NFC wireless charging applications together with data communication. The PTX30W features a single-chip solution for NFC-based wireless charging systems which harvest power, handle wireless charging protocol, and charge a Lithium-ion battery. While eliminating external discrete components, the superior RF performance of the PTX30W enables small antenna design, fast charging and allows flexible placement of Poller and Listener antennas.
