2-3 battery cells charging: IP2326 (2 cells with charging equalization)

Function Description:
USB 5V input, synchronous boost, charges 2 or 3 series batteries, maximum current at the battery end is approximately 1.5A, maximum charging power is approximately 15W.
 




Input voltage:


4.5~9.5V. 25V Max. 4.5V triggers undervoltage protection, automatically reducing charging power.




Output voltage:


2*(4.25/4.35/4345/4.65V±0.05V) .




Trickle charging


threshold: 2*(3.0V±0.05V), trickle current 50mA~150mA .




Full charge cutoff:


300mA±10mA. (When the chip output reaches 2*(4.25/4.35/4345/4.65V±0.05V), and the battery output does not reach 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


output is high during charging and low when fully charged. It flashes in case of an abnormality.




The NTC chip


supports over-temperature protection with a built-in over-temperature protection up to 135℃.
