Introduction

AI Translation

CH224Q and CH224A are fast charging sink chips supporting USB PD3.2, with a maximum supported power of PD3.2 EPR 140W. They support configuration via single resistor, I/O level, or I²C. Through the I²C interface, users can read the protocol handshake status and rated current of the current PD profile. The chips feature a built-in high-voltage LDO, low quiescent current consumption, high integration, and a simplified peripheral circuit. Output voltage detection and overvoltage protection are integrated on-chip.
