1 DESCRIPTION

The MT5715 is an SoC (System on Chip) for magnetic induction based wireless power receiver.It is fully compliant with the latest WPC Qi specification (Version 1.2.4)of BPP (Baseline Power Profile) and EPP (Extended Power Profile) and also supports various proprietary fast charging protocols used by major smart phone OEM’s. It is capable of true fast wireless charging for up to 20W of delivered power with fully programmable output voltage (maxi 20V) and current. MT5715 has a very high overall AC to DC conversion efficiency (up to 97%), thanks to the optimized and adaptive full synchronous rectifier control, very small R of power MOSFET’s, and extreme current. With the exception of a few external passive components, this SoC integrates everything that is needed for a wireless power receiving function. It is composed of a generic embedded micro controller and its associated data and program memories, spec and analog hardware co-processing units for wireless power, full synchronous rectifier and special output LDO, robust and reliable over voltage/current/temperature protection circuits, bi-directional communication unit and various GPIO’s and serial interfaces. With the flexibility of SoC architecture and the unique implementation, the MT5715 is future proof in supporting WPC Qi specification’s further updates and new proprietary protocols. It also supports “Power Sharing” mode where a wirelesspower receiver is configured into a wireless power transmitter by firmware control.
