This document introduces the characteristics and features of Micrel MIC184 Local/Remote Thermal Supervisor, including measuring local and remote temperatures, compatibility with LM75, 9-bit sigma-delta ADC, 2-wire I2C/SMBus compatible interface, programmable temperature settings, etc.
The MIC184 is a versatile digital thermal supervisor capable of measuring temperature using either its own internal sensor or an inexpensive external sensor. It features a 2-wire serial interface compatible with both I2C and SMBus masters, allowing communication with up to eight devices on the same bus.
Key characteristics include pin-for-pin and software compatibility with the industry standard LM75, programmable thermostatic settings for internal or external zones, and an open-drain interrupt output. The device operates over a power supply range of 2.7V to 5.5V and supports temperature ranges from -55°C to +125°C.
