Product Overview
The MIC384 is a versatile digital thermal supervisor designed for comprehensive temperature monitoring. It features an internal sensor and can interface with two external silicon diode sensors, making it ideal for applications requiring local and remote temperature measurements. With its 2-wire SMBus-compatible interface, programmable thermostat settings, and an open-drain interrupt output, the MIC384 offers flexible thermal management solutions. Its fault queues and failsafe response to diode faults prevent nuisance tripping and ensure reliable operation. The device supports a wide power supply range and is available in compact SOIC and MSOP packages.
