MT5727H数据手册Maxic中文资料规格书

描述 Description

MT5727H is a SoC based wireless power receiver which is designed for applications with up to 20W power delivery and can be configured as a wireless charging transmitter to provide power to other receivers. It is fully compliant with 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.

MT5727H is embedded with various protection features, such as FOD, over-voltage, over-current and over-temperature protection which guarantee the system reliability.
