MT5729 is a SoC based wireless power receiver which is designed for applications with up to 30W power delivery and can be configured as a wireless charging transmitter to power other receivers. It is fully compliant with WPC Qi Specification (V2.0) of Baseline Power Profile (BPP) and Extended Power Profile (EPP).

The AC input can be converted to fully programmable DC output voltage due to the magnetic induction charging technology.

Designed with ARM Cortex M0 processor, integrated with optimized and adaptive full synchronous rectifier control and special LDO, the chip achieves high efficiency, ultra-low bias current and very small power MOSFET RDSON.

MT5729 is embedded with various protection features, such as foreign object detection (FOD), over-voltage, over-current and over-temperature protection which guarantee the system reliability.
