Lithium-Ion Battery Charge Control IC



This IC is 4.5A switch mode charge control IC with power path with USB OTG.

Synchronous switching charge control enables power supply to system and charge control with low heat generation and high efficiency simultaneously.

Expensive current sensing resistor, Power FET, and Diode for reverse current protection are not necessary, so BOM cost can be reduced.

Product Series

Switching Charger IC
