General Description

5W-RX can deliver up to 5W as a highly-integrated single-chip wireless medium power receiver IC. As wireless power transfer systems are getting more popular, they require more fast charging and high efficiency solution. The 5W-RX wireless power receiver IC is compliant with WPC 1.2.4 standard and supports the 5W baseband power profile (BPP). The 5W power receiver integrates a synchronous rectifier, a low drop-out regulator, and communication controllers which use Amplitude Shift Keying (ASK). The chip also supports the Foreign Object Detection (FOD) extension in WPC 1.2.4. For achieving chip stability, protection tools are implemented, such as over-current-protection, over-voltage-protection, thermal shutdown, and under voltage lock-out (UVLO). Configurable analog blocks can be used independently and co-operated with the control and communication unit.
