Nisshinbo Has Launched The New R5651 Series Protection IC for 3-to-5-cell Li-ion Batteries
Battery protective functions are getting more important to ensure the safety of applications using Li-ion batteries such as power tools, cleaners, electrically assisted bikes, e-bikes, drones, storage batteries, etc.
The new multi-cell battery Protection IC has many features helping users simplify their manufacturing process. First, it reduces heat generation at large current by using a low-resistance SENSE resistor, making thermal design of a board easy. Second, separating the charge and discharge paths enables using a battery pack with low impedance. Third, thanks to the high-voltage cell monitor pins, there are no constraints on connection orders. Fourth, although the IC is designed for three-to-five-cell battery packs, it can also correspond to battery packs including six or more cells by connecting two or more ICs in cascade. The simple cascading structure contributes to reducing external components.
Additionally, the IC adopts the small TSSOP-24 package.
The Nisshinbo 's R5651 series will strengthen your products' competitive edge by achieving high accuracy and low power consumption.
