February 19, 2014, Seoul – Infineon Technologies (Korea Representative Director Seung-soo Lee)’s new ORIGA™ 3 battery management IC ensures that smartphone and tablet computer users do not experience unexpected inconveniences. The battery management IC, utilizing Infineon’s proprietary PrediGauge technology, enables highly accurate remaining charge measurement, thereby minimizing the unpleasant experience of the power suddenly shutting off.

Batteries used in mobile devices operate under very demanding conditions. To accurately calculate the charge level, the battery requires a rest period of one to two hours in an unloaded state. This is necessary to calibrate the remaining charge measurement using Open Circuit Voltage (OCV) and correct errors. However, as functions such as internet browsing, navigation, and video streaming, as well as self-updating apps like Facebook and Twitter, consume power almost constantly, charging cycles are becoming increasingly shorter and more frequent.

ORIGA 3’s PrediGauge technology improves user satisfaction by accurately calculating the remaining battery capacity under such adverse conditions. It can predict the OCV within minutes of battery rest and accurately calculate the charge status within an average of 1 percent. Consequently, it enhances consumer satisfaction by allowing maximum utilization of battery capacity without the power suddenly shutting off due to a rapid drop in the remaining charge level of smartphones or tablet computers.

Actually, JD According to a survey by Power, battery life was found to be one of the most important factors in smartphone user satisfaction (U.S. Wireless Smartphone and General Mobile Phone Satisfaction Survey, Vol. 1, Mar 2012).

Another feature of the ORIGA 3 is its precise temperature detection and the provision of inputs for various sensors, such as external temperature, strain gauges, and humidity. All information collected by this IC is transmitted to a host device (smartphone or tablet) using the MIPI BIF digital protocol. The ORIGA 3 is the first remaining capacity measurement device on the market to meet this communication standard.

Like Infineon's previous generation ORIGA products, the third-generation product features authentication capabilities as a key characteristic. As the functionality of mobile devices increases, there is a growing demand for larger battery capacities and higher charging voltages of 4.35V or higher. Consequently, using poor-quality, non-genuine batteries that are not designed to charge at these voltages can cause them to swell or even explode, potentially leading to system damage or user injury, and potentially resulting in legal difficulties or reputational damage for the manufacturer. The hardware authentication feature of the ORIGA 3 can identify non-genuine batteries, thereby protecting both consumer safety and the OEM brand image.

The authentication capabilities of ORIGA 3 are based on enhanced ECC (elliptic curve cryptography). It includes the ORIGA Digital Certificate feature, which was successfully introduced and verified in ORIGA 2, and allows the use of a unique key for each individual chip. Additionally, the third-generation product enables secure firmware updates. These features help better protect consumers from hacker attacks.
