IP2326 application:

IP2326 quality is the first in the world.

IP2326 is a boost charge management IC for 2-cell/3-cell Li-ion/Li-ion battery that supports 15W fast charge.

IP2326 integrates power MOS and adopts synchronous switch architecture, so that it only needs very few peripheral devices in application, and effectively reduces the size of the overall solution and the cost of BOM.

IP2326 boost switching charging converter operating frequency 500KHz; maximum 15W input charging, 5V input, 8V/1.0A output conversion efficiency 94%; 8V/1.5A output conversion efficiency 92%.

IP2326 has an input voltage limiting function, which can intelligently adjust the charging current and adapt to the adapter load.

IP2326 supports external pins to choose to set 2-series or 3-series lithium battery charging.

IP2326 supports external resistors to adjust charging current, charging voltage, input undervoltage threshold, input overvoltage threshold, charging timeout threshold and other parameters.

IP2326 can apply for fast charging input according to the current battery voltage to improve charging efficiency and shorten charging time.

The IP2326 integrates 2-series charge equalization circuits, which can detect the voltage of each battery during charging and protect the voltage balance of the two batteries.

IP2326 integrates NTC protection function, and can realize charging NTC protection with NTC resistor.

IP2326 only has 4*4mm QFN24 package
