2 string 3 string polymer Lithium battery charging modules with balanced TYPE C voltage 8.4V12.6V fast charging 1.2A

Basic parameters and product characteristics Input: Type-C interface, support most of the market C-port mobile phone charging the carrier, support the trigger QC fast charging to improve conversion efficiency and reduce heating, typical value: 5V.Note: Our store must activate the fast charge mode after QC is powered by the QC! Output: 8.4V (2 string of lithium batteries)/12.6V (3 string lithium batteries) Note: Our shop does not guarantee that the battery of the customer must be fully to the deadline! Generally chargingDissatisfaction or so -called charging current cannot be reached. In fact, it is not a module problem. In fact, most of them are caused by the performance of customers' battery performance and large line resistance. It is recommended to check itself.Please do not use a multimeter skewers to test the current.

Charging current: maximum 1.2A.

2 During the charging, there is a balanced function, and the equilibrium current is about 22mA.Note: The 2 string of equilibrium function needs to be welded by itself to describe a wiring schematic.Balanced functions can theoretically improve battery life and improve battery performance and safety.[3 string of lithium battery mode is not balanced!]

Protection function: Input overvoltage, owed pressure protection; output overcurrent, over pressure, short circuit protection

Charging LED indicator instructions:

The battery charging LED indicator light, the charging process is bright, the LED extinguishes after charging, and the LED flash after detecting abnormalities.

Charging detailed chip data

Main -control chip: IP2326, the following is the chip manual information. Note that the information is for reference only and does not represent the actual operating parameters of the module! The customer's customer's store does not provide after -sales support.

Charging process

IP2326 uses a complete CC/CV charging mode:

When the configuration is 2 string charging:

When the battery voltage is less than 3.7V, the battery is charged at a current of 50mA.When the battery voltage is greater than 3.7V, less than 6V, charging the battery at a current of 100mA.When the battery voltage is greater than 6V, charging the set constant current ICC; when the battery voltage is close to 8.4V, enter the constant voltage charging mode.After the battery is full of stop charging, and the input continues, if the battery voltage is less than 8V, the charging will be turned on again;

When the configuration is 3 string charging:

When the battery voltage is less than 3.7V, the battery is charged at a current of 50mA.When the battery voltage is greater than 3.7V, less than 9V, charging the battery at a current of 100mA.When the battery voltage is greater than 9V, the set constant current current is 1CC charging; when the battery voltage is close to 12.6V, enter the constant voltage charging mode.After the battery is full of stop charging, and the input continues, if the battery voltage is less than 12V, the charging will be turned on again;

After entering the constant voltage mode, if the charging current is less than 200mA, the charging is stopped after 30s, and the battery voltage is higher than the stop charging voltage; if it is higher than the stop charging voltage, the charging is stopped.Continue to test after 30s.

Enter fast charge application: IP2326 can apply for fast charge voltage through DP/DM according to the current battery voltage, through DP/DM

When the configuration is 2 string charging:

When the battery voltage VBAT = 7.8V, try to apply for a 7V input fast charging; when the configuration is 3 string of charging:

When the battery voltage VBAT = 10.5V, you will try to apply for a 9V input fast charging; if you cannot apply for fast charge input, you will always charge it with 5V input.
