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 MAX14515 high-voltage liquid lens driver features a high-voltage differential output controlled through an I²C interface. The MAX14515 uses a charge-pump-based boost converter and integrated H-bridge to provide a compact lens driver solution with minimal external components to achieve a small overall footprint suitable for small space constraints inside camera modules.The MAX14515 features an 8-bit monotonic DAC with a single differential high-voltage output controlled by a 2-wire I²C interface to set the amplitude. The high-voltage outputs are capable of delivering up to 42VRMS (min) into a 220pF liquid lens load at 1.0kHz (min).The MAX14515 also features two power-saving modes (shutdown mode and sleep mode) to minimize power consumption when the device is inactive. Shutdown mode places the device in a low-power state that resets all registers and disables the I²C interface to reduce current below 500nA (max). In sleep mode, the power-on reset circuit remains active. If no activity is detected on the I²C interface, current consumption is less than 3µA.The MAX14515 operates over the +2.7V to +5.5V supply voltage range, ideal for portable applications using lithium ion battery sources. The MAX14515 is specified over the -40°C to +85°C extended temperature range and is available in a small (1mm x 2mm) 8-bump WLP package.

The MAX16946/MAX16947 high-voltage, high-side, current-sense LDO/switches feature internal current limiting to prevent system damage due to fault conditions. The MAX16946 provides a fixed regulated 8.5V output voltage or an adjustable 3.3V to 15V output voltage. The MAX16946 can also be configured as a switch, while the MAX16947 is only available as a switch. The input voltage range for both devices extends from 4.5V to 18V (45V tolerant), making the devices ideal for providing phantom power to remote radio-frequency low-noise amplifiers (LNAs) in automotive applications. The devices monitor the load current and provide an analog output voltage proportional to the sensed load current. Accurate internal current limit protects the input supply against both overload and short-circuit conditions. Two open-drain fault indicator outputs indicate to the microprocessor when a short circuit, an open-load condition, or a short-to-battery condition exists. An overtemperature shutdown is also indicated by means of the current-sense amplifier's output voltage. A fault-blanking feature allows the devices to ignore momentary faults such as those caused by the charging of capacitive loads during hot-swapping, preventing false alarms to the system. The devices feature short-to-battery protection to latch off the internal LDO/pass switch during a short-to-battery event. During a thermal overload, the devices reduce power dissipation by going into thermal shutdown. They include an active-low, high-voltage-compatible shutdown input to place them in low-power shutdown mode.The MAX16946 is available in thermally enhanced, 16-pin TQFN-EP and QSOP-EP packages. The MAX16947 is available in a 16-pin QSOP package.

The MAX4936–MAX4939 are octal, high-voltage, transmit/receive (T/R) switches. The T/R switches are based on a diode bridge topology, and the amount of current in the diode bridges can be programmed through an SPI™ interface. All devices feature a latch-clear input to asynchronously turn off all T/R switches and put the device into a low-power shutdown mode. The MAX4936/MAX4938 include the T/R switch and grass-clipping diodes, performing both transmit and receive operations. The MAX4937/MAX4939 include just the T/R switch and perform the receive operation only. The MAX4936/MAX4938 transmit path is low impedance during high-voltage transmit and high impedance during low-voltage receive, providing isolation between the transmit and receive circuitry. The high-voltage transmit path is high bandwidth, low distortion, and low jitter. The receive path for all devices is low impedance during low-voltage receive and high impedance during high-voltage transmit, providing protection to the receive circuitry. The low-voltage receive path is high bandwidth, low noise, low distortion, and low jitter. Each T/R switch can be individually programmed on or off, allowing these devices to be used as receive path multiplexers also.The MAX4936/MAX4937 feature clamping diodes to protect the receiver input from voltage spikes due to leakage currents flowing through the T/R switches during transmission. The MAX4938/MAX4939 do not have clamping diodes and rely on clamping diodes integrated in the receiver front end. All the devices are available in a small, 56-pin, 5mm x 11mm TQFN package, and are specified over the commercial 0°C to +70°C temperature range.ApplicationsHigh-Voltage Transmit and Low-Voltage IsolationMedical/Industrial ImagingUltrasound
