ABLIC Lithium-ion Battery Protection ICs

A lithium-ion battery protection IC is an IC that monitors overcharge, overdischarge, and overcurrent to protect lithium-ion batteries, ensuring safe operation.
ABLIC has been developing and producing lithium-ion battery protection ICs since 1993, and has a track record of over 30 years in the industry. We offer a diverse lineup of approximately 2,100 battery protection ICs covering a wide range of cell counts, applications and protection functions. ABLIC also provides strong support for safety-oriented battery pack development including high accuracy, low current consumption, small and lightweight packages, cascade connection allowing connection in series for multi-cell batteries, and second protection. These features make them suitable for a wide range of applications with lithium-ion batteries, from smartphones and smartwatches to cordless power tools, UPSs, and e-bikes.
Furthermore, we provide technical support from selecting and combining optimal products to designing customized protection circuits.
