The DS28E38 is an ECDSA public key-based secure authenticator that incorporates Maxim’s patented ChipDNA™ PUF technology. ChipDNA technology involves a physically unclonable function (PUF) that enables the DS28E38 to deliver cost-effective protection against invasive physical attacks. Using the random variation of semiconductor device characteristics that naturally occur during wafer fabrication, the ChipDNA circuit generates a unique output value that is repeatable over time, temperature, and operating voltage. Attempts to probe or observe ChipDNA operation modifies the underlying circuit characteristics, preventing discovery of the unique value used by the chip cryptographic functions. The DS28E38 utilizes the ChipDNA output as key content to cryptographically secure all device stored data and optionally, under user control, as the private key for the ECDSA signing operation. With ChipDNA capability, the device provides a core set of cryptographic tools derived from integrated blocks including an asymmetric (ECC-P256) hardware engine, a FIPS/NIST-compliant true random number generator (TRNG), 2Kb of secured EEPROM, a decrement-only counter and a unique 64-bit ROM identification number (ROM ID). The ECC public/ private key capabilities operate from the NIST-defined P-256 curve to provide a FIPS 186-compliant ECDSA signature generation function. The unique ROM ID is used as a fundamental input parameter for cryptographic operations and serves as an electronic serial number within the application. The DS28E38 communicates over the single-contact 1-Wire® bus at both standard and overdrive speeds. The communication follows the 1-Wire protocol with the ROM ID acting as node address in the case of a multidevice 1-Wire network.Sample now!Explore security topics and test drive secure authenticators with the Maxim Security LabRead white paper › Read white paper ›How to Setup the DS28E38 Evaluation Kit and Perform ECDSA Authentication ChipDNA–Defend Your IoT Designs from HackersAlso see: ChipDNA Technology ›ApplicationsAuthentication of Medical Sensors and ToolsIoT Node AuthenticationPeripheral AuthenticationPrinter Cartridge Identification and AuthenticationReference Design License ManagementSecure Management of Limited Use Consumables

The device has two switches in SPDT configuration, with bidirectional current-blocking capability when the switch is off.The MAX14713 features two individual enable inputs to control each power path. Each enable input controls the corresponding path as an independent switch. However, when both paths are enabled, the internal comparator controls the path based on the voltage at input nodes. The device also features an ultra-low supply current, in the operating or off states, for longer battery life.The device is available in a 15-bump (1.2mm x 2.0mm) wafer-level package (WLP) and operates over the -40ºC to +85ºC extended temperature range.Applicationse-ReadersSmart PhonesTablet PCsWearables

The MAX14727/MAX14728/MAX14731 provide protection to valuable consumer circuits against two positive voltage faults up to +28VDC. An internal clamp also protects the devices from surges up to 100V. The devices automatically select the input source, with channel A being the primary supply.These devices feature reverse bias-blocking capabilities. Unlike other overvoltage protectors, when the devices are disabled, the voltage applied to OUT does not feed back into either INA or INB. These devices also feature two OTG enable pins (OTG_ENA, OTG_ENB) that allow OUT voltage to supply the corresponding input when OUT is higher than the output startup voltage.These overvoltage-protection devices feature high-voltage, low on-resistance (73mΩ, typ) internal FETs, effectively minimizing a voltage drop across the device. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected components. The devices also have thermal-shutdown protection against overload conditions.The overvoltage-protection threshold can be adjusted with optional external resistors to any voltage between 4V and 14V. The devices automatically choose the appropriate internal trip thresholds when the overvoltage-lockout input is set lower than the external OVLO select voltage. The internal OVLO are preset to 13.75V (typ) (MAX14727), 10V (typ) (MAX14728), or 5.92V (typ) (MAX14731).The devices are specified over the extended -40°C to +85°C temperature range, and are available in a 30-bump, wafer-level package (WLP).Applicationse-ReadersSmartphonesTablets
