Overview
Description
The PTX130W is a powerful and efficient NFC transmitter system-on-chip for NFC wireless charging applications alongside data communication. PTX130W features improved key performance parameters such as output power and RX sensitivity (-80dBc ). While eliminating EMC filter and matching components the PTX130W enables simple integration and compact design without the complexity associated with existing solutions (dual resonating circuits composed by EMC filter and antenna). The superior RF performance of PTX130W enables small antenna design, fast charging and allows 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 1% step
- NFC Forum WLC Poller functionalities
- NFC Data exchange with
- Impedance change detection for FOD
- On-Chip processing of time critical commands

NFC for charging PTX30W PTX130W
Hi, I am trying to charge 160mAh Li-Ion with PTX130W and PTX30W EVBs. I set the Constant Current to 160mA and Charge Termination to 4.1V. when I analyzed the CSV data from the GUI, I saw that the Current reduced before Vbat reacted to Vtrem.. also the GUI ...

I2C communication with NFC device fails
It is recommended to run a smoke-test to ensure that the I2C interface is working without actually using the SDK code itself. For that purpose following Python code examples can be either used directly, or re-implemented for the target system. Get yourself familiar with I2C first (refer to ...
