ID / Authentication ICs
Authentication ICs prove that a battery, cartridge, cable, or accessory is genuine, often with a unique serial number and challenge-response protocol. Engineers filter on authentication method, memory size, interface such as single-wire or I2C, and package. Compare ID and authentication IC prices, stock, and lifecycle status from distributors on Circuit Center.
Manufacturers listed in ID / Authentication ICs on Circuit Center include Analog Devices, STMicroelectronics, NXP, Microchip, ams-OSRAM and Infineon.
