MCP98242T-BE/MNYBAC: Application Field and Working Principle

The MCP98242T-BE/MNYBAC is a low cost, high accuracy digital temperature sensor from Microchip Technology Inc. that operates from -40°C to +150°C. It is designed to meet the needs of automotive, industrial, environmental, and medical major applications. The device is packaged in a small 8-pin SOIC package, providing a highly accurate temperature measurement.The MCP98242T-BE/MNYBAC is a thermal management device with a delta temperature sensing feature. It is able to measure the temperature between two points and its primary application field includes thermal management in automotive applications. The device includes two comparators to set temperature thresholds, which can be used to control an external circuit. It is an ideal choice for application areas like fan speed control, ambient air temperature regulation, and so on.The device consists of an on-board voltage regulator, a digital temperature sensor, and two individual comparators. The on-board regulator can deliver up to 200 mA. The digital temperature sensor is a thermistor that measures the temperature with an accuracy of ±1°C for temperatures ranging from -40°C to +150°C. It uses a thermistor to measure the temperature and uses its own internal circuitry to convert the measured temperature into a digital format.The two independent comparators can set temperature thresholds. They have an adjustable hysteresis within the given temperature range. These comparators are used to control an external circuit such as a fan or a cooling system. When the temperature reaches the lower threshold, the output of the comparator drives an external circuit to regulate the temperature to the set threshold. When the temperature exceeds the upper threshold, the output of the comparator drives the external circuit to reduce the temperature to the set threshold.The device also includes two low-power interrupts. These interrupts allow the device to alert the system when the higher and lower temperature thresholds are crossed. The device also includes an integrated voltage regulator that can provide up to 200 mA of regulated power for external applications.The MCP98242T-BE/MNYBAC is an ideal choice for thermal management solutions in automotive, industrial, environmental, and medical applications. It is easy-to-use, highly accurate and cost-effective, making it a great choice for those looking for a digital temperature sensor with delta temperature sensing capability.
