PMIC - Thermal Management systems are important in many electronic applications, where the effective management of heat is paramount.The MCP98242T-CE/MUY temperature sensor is a popular choice in this field, by aiding the efficient monitoring, regulation, and optimization of circuit board temperatures. This article will provide an overview of the MCP98242T-CE/MUY application field and working principle.

The MCP98242T-CE/MUY temperature sensor is a thermal protection device which provides fast response times and superior accuracy for temperature sensing applications. This temperature sensor allows for a wide operating temperature range, from –20° to 150°C, making it ideal for heating and cooling equipment, air conditioning systems, or any other thermal control applications. In addition, its accuracy is ±1°C from 25° to 100°C, and ±2°C from –20° to 125°C.

The MCP98242T-CE/MUY is designed for 2-wire SMBus/I2C and 8-pin SOIC packaging. It also provides 3.0V to 5.5V operating voltage and can be used in standard temperatures (JEDEC); automotive (-40° to 125°C); and 5.5V supply low power (LP) temperature applications. The sensor uses a magneto-resistive (MR) element to detect temperature and has internal automatic offset correction, enabling the detector to scale to small changes in temperature. The sensor also features a 9-bit resolution, providing increased accuracy and sensitivity.

The working principle of the MCP98242T-CE/MUY temperature sensor is based on its magneto-resistive sensing element. When heated, the MR resistance varies according to the temperature, and the output voltage is proportional to the logarithmic relationship between the resistance change and temperature. The temperature sensor then converts this voltage output into a digital signal for the controller to interpret. This digital signal can then be used to control the circuit, providing a temperature-regulated environment.

Aside from temperature sensing, the MCP98242T-CE/MUY temperature sensor is commonly used in various PMIC - Thermal Management applications. It can be used for a variety of tasks; from controlling fan speeds, to regulating heatsinks and heat exchangers. In addition, it can be used to regulate the temperature of power stages, high power amplifiers, and even lithium-ion batteries and chargers. By using the MR element and corresponding digital signal, the temperature can be monitored and regulated effectively.

In summary, the MCP98242T-CE/MUY temperature sensor is a versatile and accurate tool for thermal management. Its ability to detect temperatures between –20° to 150°C in ±1°C accuracy makes it suitable for a variety of electronic applications. Its 9-bit resolution, combined with automatic offset correction, provides superior accuracy and enhanced sensitivity. Furthermore, its magneto-resistive design allows for the monitoring and regulation of circuit board temperatures. As a result, the MCP98242T-CE/MUY has become a popular choice for many PMIC - Thermal Management applications.
