MT5813 is a highly integrated, high performance System on Chip (SoC) for magnetic induction based wireless power transmitter solutions. It is fully compliant with WPC Qi v1.2.4 specification, with both Baseline Power Profile (BPP) and Extended Power Profile (EPP) support. The integrated large size e-FLASH enables flexible customer function support.
MT5813 integrates High voltage Buck, 2 LDO’s, three pairs of N-MOSFET’s drivers, 4 channels of ASK demodulation Analog Front End (AFE) and 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 protection and over-temperature protection for safe operation.
The chip 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. MT5813 is able to provide flexible dead time control and phase shift generation to improve EMI performance.
The chip supports multi-protocol power adaptor interface detection and control with support of QC 2.0/3.0, SCP, FCP, etc.
MT5813 integrates an ARM Cortex M0 processor with 16KB e-Flash memory and various serial interfaces (I2C, UART, GPIO’s, etc.), offering powerful processing capabilities and code space. The reference application is available with standard firmware. Customers can easily develop the customized features with the support of library (released separately).
