Product Overview

The MIC284 is a versatile digital thermal supervisor designed for CPU thermal supervision in computing applications. It measures both local and remote temperatures using a Sigma-Delta ADC for 8-bit results. Key features include a 2-wire SMBus-compatible interface, programmable thermostat settings, open-drain interrupt and overtemperature output pins for fan control or hardware shutdown, interrupt masking, low power shutdown mode, and failsafe response to diode faults. It operates from a 2.7V to 5.5V supply and is available in 8-lead SOIC and MSOP packages. Applications include desktop, server, and notebook computers, power supplies, test and measurement equipment, wireless systems, and networking/datacom hardware.
