The Microchip Technology MCP9805-BE/ST is a digital temperature sensor designed for precise temperature monitoring. It converts temperatures within the range of -40°C to +125°C into a digital word, meeting JEDEC standard JC42.4 for Mobile Platform Memory Module Thermal Sensors.
This sensor offers an accuracy of ±3°C (max.) across its operating range, with specific accuracies of ±1°C (max.) from +75°C to +95°C and ±2°C (max.) from +40°C to +125°C. It operates with a voltage range of 3.0V to 3.6V and features a 2-wire SMBus/Standard mode I2C compatible interface. The device consumes a typical operating current of 200 µA and a shutdown current of 0.1 µA.
Key features include user-programmable registers for flexible settings, such as shutdown or low-power modes, and the specification of temperature event and critical output boundaries. The MCP9805 provides an Event signal that can be configured as an active-low or active-high comparator output for thermostat operation, or as a temperature event interrupt output. It can also be configured as a critical temperature output.
The MCP9805-BE/ST is available in an 8-TSSOP package suitable for surface mounting. Its typical applications include Dual In-line Memory Modules (DIMMs), Personal Computers (PCs) and Servers, Hard Disk Drives, and other PC peripherals, making it a versatile general-purpose temperature sensor.
