It communicates over an I²C/SMBus interface and resolves temperature to 7 bits. This makes it a fit for thermal management in enclosures where the ambient spans from cold start to full-load soak. The 8-SOIC package is a standard footprint that routes easily on a two-layer board. ## Active production and compliance position The part ships in a tube — the standard 8-SOIC carrier. Surface-mount assembly with a reflow profile matching JEDEC MSL-1 is straightforward; no special handling beyond basic moisture sensitivity applies. ## Features that matter in a thermal management loop The MIC284-3YM includes an output switch, programmable temperature limit, shutdown mode, and standby mode. The programmable limit lets the sensor assert an interrupt or control a fan directly without polling the I²C bus — useful in a closed-loop thermal management system where the host MCU can sleep until the threshold is crossed. Shutdown mode drops the supply current to near-zero for battery-powered gear; standby mode keeps the digital interface alive while stopping temperature conversions. Both are controlled over the I²C/SMBus interface.","metaTitle":"MIC284-3YM Microchip Digital Temp Sensor, ±2°C, 8-SOIC","metaDescription":"MIC284-3YM digital temperature sensor from Microchip Technology. ±2°C accuracy, I²C/SMBus output, -55°C to 125°C range.
