The DS7505 low-voltage (1.7V to 3.7V) digital thermometer and thermostat provides 9-, 10-, 11-, or 12-bit digital temperature readings over a -55°C to +125°C range with ±0.5°C accuracy over a -0°C to +70°C range. A 9-bit resolution mode is software compatible with the LM75.The DS7505 thermostat has a dedicated open-drain output (O.S.) and programmable fault tolerance, which allows the user to define the number of consecutive error conditions that must occur before O.S. is activated. There are two thermostatic operating modes that control thermostat operation based on user-defined trip points (TOS and THYST) that are stored in EEPROM registers.ApplicationsAny Thermally Sensitive SystemCellular Base StationsMedical EquipmentNetworking EquipmentOffice Equipment

This low-voltage (1.7V to 3.7V) digital thermometerand thermostat provides 9, 10, 11, or 12-bit digitaltemperature readings over a -55°C to +125°C rangewith ±2°C accuracy over a -25°C to +100°C range. Atpower-up, the DS75LX defaults to 9-bit resolution forsoftware compatibility with the LM75. Communicationwith the DS75LX is achieved through a simple 2-wireserial interface. Three tri-state address pins allow upto 27 DS75LX devices to operate on the same 2-wirebus, which greatly simplifies distributed temperature-sensingapplications.The DS75LX thermostat has a dedicated open-drainoutput (O.S.) and programmable fault tolerance,which allow the user to define the number ofconsecutive error conditions that must occur beforeO.S. is activated.

The MAX6639 monitors its own temperature and one external diode-connected transistor or the temperatures of two external diode-connected transistors, typically available in CPUs, FPGAs, or GPUs. The 2-wire serial interface accepts standard System Management Bus (SMBus) write byte, read byte, send byte, and receive byte commands to read the temperature data and program the alarm thresholds. Temperature data can be read at any time over the SMBus, and three programmable alarm outputs can be used to generate interrupts, throttle signals, or overtemperature shutdown signals.The temperature data is also used by the internal dual-PWM fan-speed controller to adjust the speed of up to two cooling fans, thereby minimizing noise when the system is running cool, but providing maximum cooling when power dissipation increases. Speed control is accomplished by tachometer feedback from the fan, so that the speed of the fan is controlled, not just the PWM duty cycle. Accuracy of speed measurement is ±4%.The MAX6639 is available in 16-pin QSOP and 16-pin thin QFN 5mm x 5mm packages. It operates from 3.0V to 3.6V and consumes just 500µA of supply current.ApplicationsDesktop ComputersNetworking EquipmentNotebook ComputersProjectorsServers
