描述 Description

MT5728 is a SoC based wireless power receiver which is designed for application with up to 30W power delivery and can be configured as a wireless charging transmitter to provide power to other receiver. It is fully compliant with the WPC Qi Specification (Version 1.2.4).

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.

MT5728 is embedded with various protection features, such as FOD, over-voltage, over-current and over-temperature protection which guarantee the system reliability.
