PTX30W is the industry’s only integrated, single-chip solution for the listener circuit in NFC wireless charging systems.
The PTX30W, which is supplied in a compact 3.2mm2 WL-CSP package, enables manufacturers of small battery-powered products to implement NFC wireless charging with a board which is around four times smaller than existing designs based on multiple discrete components.
The fully autonomous PTX30W runs an NFC Forum-derived wireless charging protocol which supports power negotiation. This means that the PTX30W can operate in stand-alone mode with no need for an external microcontroller to run NFC wireless charging operations.
