概要
説明
The PTX30W is an efficient single-chip NFC Receiver for NFC wireless charging applications including bi-directional data transfer. The PTX30W is a highly integrated solution for NFC-based wireless charging systems combining power harvesting, wireless power negotiation, and charging of a Lithium-Ion battery in a single chip.
The integration reduces the required number of external components. Combined with its RF performance it is well suited for integration into space constrained devices enabling fast charging and maximum flexibility in the system design.
