Published:2011/12/2 1:31:00 Author:Amy From:SeekIC

Renesas Electronics Corporation, a premiere supplier of advanced semiconductor solutions, recently launched a charging control integrated circuit (IC) R2A20055NS. It has further miniaturization and safe charging control for single-cell lithium-ion batteries. In addition to the full complement of protection features, including battery overvoltage protection and charging timers, the new IC includes functions that implement the charging profiles stipulated by JEITA, which enable the R2A20055NS IC to implement safe charging control. It offers control pins for each block to limit the input current. Current limit are availavle in 100 mA, 500 mA, or no limit; thus, it can perform battery charging according to the USB power available. The withstand voltage of the R2A20055NS input is 25 V, and the company has added new overvoltage protection functions to the input pins. These can protect application systems from the overshoot that occurs when a power adapter or USB cable is connected. The IC implements the functions in a 2.0 × 2.5 millimeter (mm) ultra-miniature, high thermal dissipation, 10-pin HUSON package, and thus can contribute to further miniaturization in portable equipment.

Renesas Electronics Corporation is the world’s number one supplier of microcontrollers as well as advanced semiconductor solutions including microcontrollers, SoC solutions and a broad range of analog and power devices, and LCD modules, for the Americas’ market.
