It reads temperature from both an internal sensor and an external diode-connected transistor, reporting values with ±2°C accuracy over the measurement range. ## What ±2°C accuracy buys in a thermal management loop The ±2°C accuracy means the controller can trigger a fan-speed change or an overtemperature alarm within a tight thermal window — important when a 3°C margin separates normal operation from a derating event or system shutdown. The on-chip sigma-delta ADC converts the temperature reading into a digital word that the SMBus interface transmits to the host; the register bank holds the limit thresholds and fan-control parameters locally, so the host does not have to poll continuously. ## 16-QFN package and 3.3V supply rail It runs from a single 3.3V supply, which is common in server, telecom, and industrial control backplanes where the fan tachometer and SMBus already share that rail. ## Active lifecycle and compliance baseline It is offered in both Tape & Reel for automated pick-and-place and Cut Tape for prototype or low-volume builds.","metaTitle":"EMC2103-4-AP-TR Fan Controller, ±2°C Temp Monitor, 16-QFN","metaDescription":"Microchip EMC2103-4-AP-TR fan controller with ±2°C accuracy, internal/external temp sensing, SMBus interface, 3.3V supply.
