Product Description
Product Overview
The MIC384 is a versatile digital thermal supervisor designed to measure local and two remote temperatures. It features a 2-wire SMBus-compatible interface, programmable thermostat settings, and an open-drain interrupt output. Its fault queues and failsafe response to diode faults prevent nuisance tripping. With a low power shutdown mode and a wide operating voltage range, the MIC384 is ideal for demanding thermal management applications in computers, power supplies, and networking hardware.
