DESCRIPTION
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 v1.2.4 specification, with both Baseline Power Profile (BPP) and Extended Power Profile (EPP) support. The integrated large size eFlash enables flexible customer function support.
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.
