Microchip Introduces Portable Battery Authentication Safety Solution

9/24/2004 - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced its KEELOQ® secure algorithm, used worldwide by leading automotive manufacturers, can now be used for battery authentication in portable applications. This technology adds a low-cost safety layer in portable electronics, such as a cell phone, “to identify” if the battery pack in a charger or system is “friend” (factory authorized) or “foe” (counterfeit), a concept known as IFF.

Microchip’s KEELOQ cryptographic technology is a proprietary encryption and decryption algorithm. This technology enables the host system or charger to determine if a battery provides optimum performance and safety to the user. The KEELOQ cryptographic algorithm can be integrated into any of Microchip’s microcontrollers and many of Microchip’s battery fuel gauge integrated circuits. These components are then integrated within the battery pack and host system to provide one of the industry’s most secure authentication solutions for battery-operated devices.

“In many situations, it can be extremely important to verify the compatibility of a replacement battery in order to ensure the system performs to specifications, maintains quality standards and/or allows safe operation of the whole system. Batteries can be based on a number of technologies (NiCd, NiMH, Li Ion, etc.) that, in turn, require different charge or discharge profiles. Even the same battery chemistry may function differently within a system, depending on the battery-management settings and pack design. As seen in recent incidents, a mismatched battery could lead to potentially dangerous situations severely compromising the safety of the end user,” said Jim Vernon, vice president of Microchip’s Battery Management Product Division.
