Overview
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.
Applications
- Wireless chargers
- Small appliances
- Lithium battery power tools
- Mobile devices
Key features
- 4V to 30V input voltage range
- Supports PD3.2 EPR, AVS, PPS, SPR, and BC1.2 fast charging protocols
- eMarker emulation with automatic VCONN detection
- Multiple methods for dynamic voltage request adjustment
- I²C communication at 400 KHz
- Integrated high-voltage LDO, low quiescent current consumption
- High integration single-chip design with simplified peripheral circuitry and low cost
- Built-in overvoltage protection module
