SGMICRO SGM457XKB6G/TR

The SGM457 is a low-power, low-supply-voltage temperature sensor in an SOT package with a serial control interface and digital output, offering ±0.5°C accuracy (typical) over a temperature range of -40°C to +125°C. Communication with the SGM457 is via an I²C interface. The serial bus supports multi-device access commands, allowing up to four SGM457 devices to share a single serial bus. A microcontroller can communicate with these devices on the bus without sending separate commands, improving software efficiency. In multi-hotspot monitoring systems such as computing platforms, multiple temperature sensors can be connected on a single serial bus to simplify design. The SGM457 is available in a RoHS-compliant SOT-563-6 package and operates over an ambient temperature range of -40°C to +125°C.
