• Environmental monitoring
• HVAC systems
• Consumer electronics
• Power supply temperature monitoring
• Battery management systems
• Automotive applications

Features:

• Digital temperature sensor
• ±2°C accuracy (typical)
• I2C interface for communication
• Wide operating voltage range (2.7V to 5.5V)
• Low power consumption
• Programmable temperature thresholds
• Alert/Interrupt output

Benefits:

Additional Details:

The FM75MB typically comes in a small outline package (SOIC). It communicates with a host microcontroller using the I2C serial interface. The device includes programmable temperature thresholds that can be used to generate an alert signal when the temperature exceeds or falls below predefined limits. The I2C address is configurable, allowing multiple sensors to be connected to the same I2C bus. It operates over a temperature range of -40°C to +125°C.
