ET73224Q

ET73224 integrates multiple fast charging protocols such as USB PD3.0/2.0, BC1.2, automatically detects VCONN and simulates E-Mark chips, and supports up to 100W power. ET73224 has a built-in PD communication module, with features of high integration and streamlined peripherals. It integrates output voltage detection function, and provides over-temperature and over-voltage protection functions, etc. It can be widely used in various electronic equipment to expand high-power input, such as wireless charger, electric toothbrush, rechargeable shaver, lithium battery power tools and other application scenarios. ET73224Q is a USB PD fast charging protocol receiver chip that supports USB PD3.2, up to PD3.2 EPR 140W power, and supports single resistor configuration, I/O level configuration and I2C configuration. Through the I2C interface can read the protocol handshake status and read the current PD gear rated current.
