DESCRIPTION
It integrates everything except power MOSFET’s and a few passive components. These include high voltage Buck, LDO’s, three pairs of N-MOSFET’s drivers (to support two coils applications), multiple channels of unique Analog Front End (AFE) for ASK demodulation, FOD and Q factor detection, powerful and unique DSP for demodulation and FOD, generic 12 bit ADC and DAC, current sensing and Over Voltage, Over Current and Under Voltage Protection (OVP, OCP, UVP), oscillators and PLL with support of external crystal for high accuracy clock and extremely low power deep sleep mode, plenty of channels of PWM for individual control of each power MOSFET’s for flexible dead time control and phase shift generation, power adaptor interface detection and control with support of QC 2.0/3.0, USB PD, SCP, FCP and AFC, etc. As the control and configuration center as well as data processor, MT5815 integrates an ARM Cortex M0 processor with a spacious 64KByte eFlash memory and 4KByte SRAM, as well as various serial interfaces (I2C, UART, GPIO’s, etc.), offering powerful processing capabilities and customized features.
