DATA SHEET AND USECASE

Key Features:

• I²C Interface: Facilitates communication with up to eight devices on the same bus, selectable via three address pins.
• Over-Temperature Shutdown (OS): An open-drain output that becomes active when the temperature exceeds a user-defined limit, configurable for interrupt or comparator modes.
• Programmable Temperature Thresholds: Allows setting of over-temperature shutdown (TOS) and hysteresis (THYST) limits for precise thermal management.
• Stand-Alone Thermostat Operation: Defaults to comparator mode with TOS set to 80°C and THYST to 75°C upon power-up, enabling immediate operation without additional programming.
