Microchip Technology is a leading innovator and supplier of high performance and high quality embedded solutions and microcontrollers; related non-volatile memory products; and a broad analog product line focusing on power management, thermal management, linear and mixed-signal solutions.

Temperature sensing is critical to a growing number of consumer, automotive, and industrial applications. Microchip’s digital temperature sensors are ideal choice for implementing temperature system management schemes in a variety of applications.

MCP9800/1/2/3 – 2-Wire High Accuracy Temperature Sensor

MCP9800/1/2/3 family of digital temperature sensors converts temperatures between -55°C and +125°C to a digital word. They provide an accuracy of ±1°C (max.) from -10°C to +85°C.

The MCP9800/1/2/3 family comes with user-programmable registers that allow user selectable 9-bit to 12-bit measurement resolution, configuration of the power-saving Shutdown and One-shot (single conversion on command while in the Shutdown) modes and the specification of both temperature alert output and hysteresis limits.

The MCP9800/1/2/3 notifies the host controller when the ambient temperature exceeds a user programmed set point. The ALERT output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt.

The MCP9800/1/2/3 uses an industry standard 2-wire, I2C™/ SMBus compatible serial interface, allowing up to eight devices to be controlled in a single serial bus. These features make the MCP9800/1/2/3 ideal for sophisticated multi-zone temperature-monitoring applications.

The MCP9800/02 device address is factory-set. The MCP9801/03 offers three address input pins that are customer-selectable. Furthermore, the MCP9801/03 have SMBus Timeout logic (35 ms typical) for improved system reliability. The I2C™ specification does not limit clock speed and, therefore, time-out is not available on MCP9800/01. 

The MCP9803T-M/SN is a SOIC (narrow) High Accuracy Temperature Sensor that comes in a 3300 piece reel.
