Do you know about lithium-ion battery charging IC equipped with current path function?

What is a lithium-ion battery charging IC equipped with a current path function? What does it do? Torex Semiconductor Co., Ltd. (Managing Director, Chuo-ku, Tokyo, Japan: Koji Shibamiya; Second Tokyo Stock Exchange: 6616) has developed Current path function, charging IC for 1-cell lithium ion/polymer secondary battery (hereinafter referred to as lithium battery) [XC6806 series product].

The [XC6806 series products] developed by Torex this time are equipped with a current path function that can control the current for charging the battery and providing the system to an exact value. Compared with conventional products, the voltage at which charging is completed can be set within a wider range, and it can also be adapted to a variety of lithium batteries (charging voltage range: 3.5V to 4.45V). In addition, it is equipped with a shutdown function that completely stops the power supply from the battery to the machine. Because the battery leakage current can be suppressed to 100nA when the device is not in use, low-current consumption devices powered by small batteries can be used for a longer period of time.

It adopts USP-10B (2.9x2.6xh0.6mm) and LGA-10B01 (2.5 x 1.6 x h0.4mm) package components that are small and have excellent heat dissipation properties. You can choose the package according to the application.

Torex will continue to rapidly develop products based on market demand and continue to contribute to the realization of a prosperous society.
