The SGM458 is a low power, low supply voltage, CSP package, serial control interface and digital output temperature sensor with an accuracy of ±1℃ (TYP) in the temperature range of -55℃ to +125℃. The serial two-wire interface supports traditional I2C bus or SMBus interface. Multiple device access instruction is used in this serial bus, so multiple SGM458 devices (up to three) 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 SGM458 has a power supply voltage range of 1.6V to 5.5V, so the 1.8V I/O of the micro-controller can be used as the power supply of SGM458.
The SGM458 is available in a Green WLCSP-0.85×0.85-4B package and specified over a temperature range of -55℃ to +125℃.
