Texas Instruments LM87CIMT is a versatile hardware monitoring IC designed for precise temperature and fan speed management. This component features internal and external temperature sensing capabilities, operating across a wide temperature range of -40°C to 125°C. The LM87CIMT offers a 2-Wire Serial, I2C/SMBUS output interface for seamless integration into system monitoring architectures. Its 24-TSSOP package is suitable for surface-mount applications. Key functionalities include ADC (Sigma Delta) for accurate measurement, comparator logic, fan speed counting, and an internal register bank for configuration. The device supports a supply voltage range of 2.8V to 3.8V and includes a fan output for speed control. Typical applications span industrial control, networking equipment, and consumer electronics requiring robust thermal oversight. Accuracy for local temperature sensing is ±3°C (Typ), and ±4°C (Max) for remote sensing.
