MIC384-3BM
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, an open-drain interrupt output, and fault queues to prevent nuisance tripping. Its low power shutdown mode and failsafe response to diode faults make it suitable for demanding thermal management applications.
