The SGM459 is an industry standard digital temperature sensor which integrates sigma-delta analog-to-digital converter (ADC) and I2C interface. This device is accurate to ±1.2℃ in the range of -55℃ to +125℃. The SGM459 offers 12-bit digital temperature readings.
The power supply voltage of the device is from 2.7V to 5.5V. I2C interface is used to communicate with SGM459 devices and it operates up to 400kHz.There are three address pins of the devices to support eight SGM459 at most on the same I2C bus. There is an appropriative over-temperature output with programmable limit and hysteresis on SGM459. The programmable fault tolerance of the output can define the number of consecutive error conditions that must occur before OS is activated. The wide temperature, wide power supply range and I2C interface make the SGM459 ideal for plenty of applications in which thermal management is critical for performance, such as wireless base stations, notebook computers, personal computers, etc.
The SGM459 is available in a Green TDFN-2×2-8AL package and operates over an ambient temperature range of -55℃ to +125℃.
