INJOINIC IP2183_D

IP2183_D is a highly integrated fast charging protocol IC for USB output ports. Its primary function is to parse fast charging requests from devices connected to the USB port, and then notify the USB port to adjust the output voltage according to the parsed fast charging protocol. IP2183_D supports automatic detection of the charging protocol type of devices connected to the USB port and performs protocol switching, enabling it to respond to charging voltage requests from different protocols.

IP2183_D supports multiple protocol parsing for USB ports, including HVDCP QC3.0/QC2.0 (Quick Charge) Class A, FCP (Hisilicon Fast Charge Protocol), SCP (Hisilicon Super Fast Charge), AFC (Samsung Adaptive Fast Charge), MTK PE+ 2.0/1.1 (MediaTek Pump Express Plus 2.0/1.1), as well as Apple 2.4A, Samsung 2.0A, and BC1.2 charging protocols.

IP2183_D monitors the DP and DM pin voltages in real time. When a non-fast-charging device is detected at the USB port, it performs handshaking with different devices by varying the voltages on the DP and DM pins. When a fast-charging device is detected at the USB port, it automatically identifies the fast charging type, parses and responds to the protocol request to complete the handshaking process with the device, and then sources or sinks current through the FB pin in accordance with the protocol request to adjust the feedback voltage of the feedback loop, thereby regulating the fast charging voltage. When the output voltage is at the default 5V, the FB pin makes no adjustment. IP2183_D does not control the charging loop; the actual charging loop and charging current are determined by the adapter and the connected USB port device.
