The SGM457 is a low power, low supply voltage, SOT package, serial control interface and digital output temperature sensor with an accuracy of ±0.5℃ (TYP) in the temperature range of -40℃ to +125℃. I2C interface is used to communicate with SGM457. Multiple device access instruction is used in this serial bus, so multiple SGM457 devices (up to four) can share one serial bus. The micro-controller will communicate with these devices on the bus without sending separate instructions which increases the efficiency of software. In multiple hot points monitoring systems such as computing platform, the design can be realized by connecting one serial bus with multiple temperature sensors.
The SGM457 is available in a Green SOT-563-6 package and operates over an ambient temperature range of -40℃ to +125℃.
