The MAX31827 is a ±1°C accuracy from -40°C to +125°C (12 bits) local temperature switch and sensor with I2C/SMBus interface. The combination of small 6-bump wafer-level package (WLP) and high accuracy makes this temperature sensor/switch ideal for a wide range of applications. It can be used as a temperature switch with preconfigured thresholds and/or as a temperature sensor with I2C interface. When the part operates as an independent temperature switch, the I2C interface doesn't have to be used. This enables use of the part in systems that require thermal protection implemented in hardware, without the need for reconfiguration or use of software/firmware during normal operation.One-time programmable (OTP) ALARM functionality enables use of the part as a safety mechanism in systems where power dissipation is a challenge.The I2C/SMBus-compatible serial interface accepts standard write and read commands to read the temperature data and configure the behavior of the sensor. Bus timeout resets the interface if the clock is low for more than 30ms (nominal). Packet error checking (PEC) helps prevent communication errors when used with a master that supports this feature.TheMAX31827is available in a 6-bump WLP and operates over the -45°C to +145°C temperature range.ApplicationsBattery-Powered EquipmentData Communications EquipmentHandheld ElectronicsIndustrial EquipmentServers

The MAX3180E-MAX3183E single RS-232 receivers in a SOT23-5 package are designed for space- and cost-constrained applications requiring minimal RS-232 communications. The receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, to ±8kV using IEC 1000-4-2 Contact Discharge, and to ±15kV per the Human Body Model, ensuring compliance with international standards.The devices minimize power and heat dissipation by consuming only 0.5µA supply current from a +3.0V to +5.5V supply, and they guarantee true RS-232 performance up to a 1.5Mbps data rate. The MAX3180E/MAX3182E feature a three-state TTL/CMOS receiver output that is controlled by an active-low EN logic input. The MAX3181E/MAX3183E feature an active-low INVALID output that indicates valid RS-232 signals at the receiver input for applications requiring automatic system wake-up. The MAX3182E/MAX3183E have a noninverting output, while the MAX3180E/MAX3181E have a standard inverting output.ApplicationsDiagnostic PortsDigital Still CamerasHandheld EquipmentNetwork EquipmentSet-Top BoxesTelecommunications

The MAX3185 is a complete DTE RS-232 serial port designed to meet the stringent ESD requirements of the European community. All transmitter outputs and receiver inputs are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model.The MAX3185 has three RS-232 transmitters, five RS-232 receivers, and no charge pump, optimizing it for operation in desktop PC and motherboard applications. It is guaranteed to run at data rates up to 230kbps, providing compatibility with popular software for communicating with personal computers. Power-supply current is less than 300µA for IDDand ISS, and less than 1mA for ICC.The MAX3185 is pin and functionally compatible with the industry-standard 75185, so existing designs can instantly become EMC compliant. The MAX3185 is available in an SO package and in the tiny SSOP that further reduces board space.ApplicationsComputers: Desktop, Workstation, ServerEquipment Meeting IEC 1000-4-2InstrumentsMotherboards

The MAX31850/MAX31851 cold-junction compensated, 1-Wire®thermocouple-to-digital converters perform cold-junction compensation and digitize the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The converters resolve temperatures to 0.25°C, allow readings as high as +1768°C and as low as -270°C, and exhibit thermocouple accuracy of 8 LSBs (2°C) for temperatures ranging from -200°C to +700°C.Communication with the master microcontroller is over a 1-Wire bus that by definition requires only one data line (and ground) for communication. Operating power can be obtained directly from the data line ("parasite power"), eliminating the need for an external power supply.Each device has a unique 64-bit serial code, which allows multiple units to function on the same 1-Wire bus. Therefore, it is simple to use one microcontroller (the master device) to monitor temperature from many thermocouples distributed over a large area.Four location address inputs simplify mapping of individual units to specific locations.ApplicationsAppliancesHVACIndustrialMedical
