MICROCHIP AT30TS74-UFM14-T-072

The AT30TS74 is a complete, precise temperature monitoring device designed for use in a variety of applications which require the measuring of local temperatures as an integral part of the system's function and/or reliability. The AT30TS74 device combines a high-precision digital temperature sensor, programmable high and low temperature alarms, and a 2-Wire I²C and SMBus (System Management Bus) compatible serial interface into a single compact package. The temperature sensor can measure temperatures over the full -55℃ to +125℃ temperature range and has a maximum accuracy of ±2.0℃ from -20℃ to +100℃. The result of the digitized temperature measurements are stored in one of the AT30TS74 internal registers, which is readable at any time through the device's serial interface. The AT30TS74 utilizes flexible, user-programmable internal registers to configure the temperature sensor's performance and response to high and low temperature conditions. A dedicated alarm output activates if the temperature measurement exceeds the user-defined temperature and fault count limits. To reduce current consumption and save power, the AT30TS74 features a Shutdown mode which turns off all internal circuitry except for the internal Power-On Reset (POR) and serial interface circuits. The AT30TS74 is factory-calibrated and requires no external components to measure temperature. With its flexibility and high-degree of accuracy, the AT30TS74 is ideal for extended temperature measurements in a wide variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.
