MT5810 is a highly integrated, high-performance System on Chip (SoC) for magnetic induction based wireless power transmitter solutions. It is fully compliant with the Wireless Power Consortium (WPC) Qi V2.0 specification, supporting both BPP and EPP. The integrated large size e-Flash enables flexible customer function.

MT5810 integrates 1.5V LDO, four channels of ASK demodulation Analog Front End (AFE), 16 channels of ASK demodulation DSP. The embedded precise low-side current sensing, generic 10-bit ADC and DAC enable high-performance FOD and Q factor detection.

It supports over-voltage, over-current, under-voltage and over-temperature protection (OVP, OCP, UVP, OTP) for safe operation.

MT5810 integrates separated high-frequency and low-frequency oscillators for low-power and low-cost application. The internal high-frequency PLL with support of external crystal is designed for high accuracy clock and PWM signal generation. MT5810 is able to provide flexible dead time control and phase shift generation to improve EMI performance.

MT5810 supports multi-protocol power adaptor interface detection and control with support of QC 2.0/3.0, USB PD, SCP, FCP, etc.

MT5810 integrates an ARM Cortex M0 processor with 64kB e-Flash memory and various serial interfaces (I²C, UART, GPIO, etc.), offering powerful processing capabilities and code space. The reference application is available with standard firmware. With the support of library (released separately), customers can easily develop customized features.
