MT2801

MT2801 is a highly integrated System on Chip (SoC) based multi-protocol controller. It supports USB PD3.2 R1.0, functioning as a downstream facing port (DFP) with programmable power supply (PPS) or as a dual- role port (DRP) via CC1/CC2 pins. It also supports multiple fast charging protocols like BC1.2, QC2.0, QC3.0, SCP, UFCS, AFC etc.

MT2801 integrates a high-resolution regulator, constant voltage (CV) loop and constant current (CC) loop, utilizing a digital-to-analog converter (DAC) for accurate reference voltage. It can also regulate the external DC-DC controller through FB pin with CV and CC loop.

MT2801 can share the output power through master/slave I²C communication. The chip features multiple configurable general-purpose I/Os (GPIO), enabling flexible application customization.

Designed with ARM Cortex M0 processor, 32kB ROM and 16kB MTP, the chip is applicable to various applications.

MT2801 is embedded with various protection features, such as over-voltage protection (OVP), over-current protection (OCP) and overtemperature protection (OTP) to ensure the system reliability.
