IP2363 30W fast charging for 2-5 battery cells

The
IP2363 supports 5V/9V/12V/15V/20V USB fast charging input, as well as 5~24V DC input.
It is a synchronous buck-boost charging management chip for charging 2~5 cells in series, with a maximum charging power of approximately 30W.
 




Input voltage


is 4.5~25V, 30V Max. Undervoltage protection is triggered at 4.5V, automatically reducing charging power.




Output voltage is


N*(4.2V/3.65V±0.05V) (other specifications can be customized).




Trickle charging


threshold is N*(3.0V±0.05V), trickle current is 200mA±100mA,




and full charge cutoff


is 100mA. (When the chip output reaches N*(4.2V/3.65V±0.05V), and the battery output has not reached it, the charging process switches from constant current charging to constant voltage charging. The higher the internal resistance of the battery cell and wires, the longer the constant voltage charging time.)




The LED


lights up red during charging and green when fully charged.




The NTC chip


supports over-temperature protection (125℃).

The IP2363 chip contains firmware. Please carefully confirm the firmware's functions, version information, etc., with your supplier. 2. The MOSFETs used in the IP2363's external buck-boost circuit should not be easily replaced. The precise parameters of the MOSFETs will have a significant impact on the overall buck-boost efficiency. Unless your IP2363 supplier ensures that there are matching MOSFET models available in large quantities, do not easily change the PCB layout diagram, PCB 3D preview image, PCB physical image , and other design files . Please obtain these from your supplier.
