Digital local/remote sensing with I²C/SMBus interface
The MIC281-2BM6TR: This is a digital temperature sensor that measures both its own die temperature (local) and an external diode-connected transistor (remote) over an I²C or SMBus two-wire bus. For most system monitoring tasks — over-temperature trip points, fan control, thermal throttling — that is tight enough to act on without calibration.
SOT-23-6 footprint and supply rails
Housed in a standard SOT-23-6 surface-mount package, the same footprint as many small op-amps and logic buffers. A shutdown mode pin (or register bit, depending on the variant) lets the sensor drop into a low-power state when the system is idle — handy for battery-powered gear where every microamp counts.
RoHS non-compliant — check your BOM's environmental requirements
The MIC281-2BM6TR is marked RoHS non-compliant by Microchip. If your assembly must meet EU RoHS or REACH directives, this part will not pass — plan for an exemption or a compliant alternative.
