Charge and Discharge Path Management

Standby:

If VIN or VBUS is attached ，IP5568 will start the charging process directly.

If USB C UFP device is attached on VBUS or sink device is attached on VOUT port, IP5568 will start discharge

function automatically.

If key is pressed, the VOUT1、VOUT2 and USB C port will open only when load is detected on the according

port, or the output on these port will be closed.

Discharge:

In the case of no key action, only the output path of the output port plugged in the electrical equipment will

be opened; the output path of the output port not connected to the equipment will not be opened. When the

output current of the opened output port is less than about 80mA, it will automatically close after a period of

time.

Any port of Vout1, vout2 and USB C can support the output fast charging protocol. However, since this

application is a single inductance application, it can only support one voltage output, so it can only support the

fast charging output when only one output port is open. When two or three outlets are used at the same time,

the quick charge function will be automatically turned off.

According to the connection shown in the "typical application diagram", when any output port has entered

the fast charging output mode, when the other output port is plugged in with electrical equipment, all the output

ports will be closed first, the high-voltage fast charging function will be closed, and then the output ports with

equipment will be opened. In this case, all the output ports only support the charging of apple, Samsung and

bc1.2 modes. When the number of electrical equipment is reduced to only one, after 16 seconds, all output ports

will be closed first, the high-voltage fast charging function will be turned on, and then the output port of the last

electrical equipment will be turned on, so as to reactivate the equipment to request fast charging. When only one

output port is open and the total output current is less than about 80mA for about 32S, the output port and

discharge function will be closed and the standby mode will be entered.

When the wireless charging TX, VOUT1, VOUT2, and VBUS have any two outputs at the same time,

the boost output can only be 5v.

When the wireless charging TX, VOUT1, VOUT2, and VBUS have only one outputs, boost can

output the quick charging.

TX can only transmit 10w/15W power when VOUT1, VOUT2 and VBUS are shut down.

Charging：

Any port of VIN port and VBUS port can be charged by inserting the power supply. If both ports are

connected to the power supply for charging, the first inserted power supply will be used for charging.

In the single charging mode, the fast charging mode of the power supply will be automatically identified, and

the appropriate charging voltage and current will be automatically matched

When only VIN and TX work, and VIN can apply for 9V high voltage, the wireless charging TX can transmit

10w power. When VIN can apply 12V high voltage, the wireless charging TX can transmit 15w power.

When only VBUS and TX work, and VBUS can apply for 9V high voltage, the wireless charging TX can transmit

10w power. When VBUS can apply 12V high voltage, the wireless charging TX can transmit 15w power.

Charging and discharging at the Same Time：

When the charging power supply and the electrical equipment are plugged in at the same time, the charging

and discharging mode will be automatically entered. In this mode, the chip will automatically turn off the internal
