JD6610Q also supports USB BC 1.2 and Apple 2.4A charging, ensuring broad compatibility with mainstream devices and delivering stable charging performance. If a connected device does not support QC, FCP, SCP, or AFC protocols, the chip automatically disables voltage adjustment and maintains a safe 5V output to ensure system stability and reliability. 

Additionally, the JD6610Q features Constant Voltage (CV) mode, making it ideal for applications that require precise voltage control. This ensures accurate output voltage regulation, meeting the needs of high-precision power applications. 

The chip is available in a compact SOT-23-6L package, making it suitable for wall adapters, car chargers, and USB power output ports, providing an efficient and highly integrated power solution.
