PMIC stands for Power Management IC, which is an integrated circuit that is used to monitor and control the supply voltages, current supplies, temperature, and other electrical parameters. Thermal management, which refers to the control of heat within an electronics system, is an essential part of power management. The MCP98243-BE/ST, which is a temperature sensor, is one of the ways in which PMIC can be used for temperature management. This article will look at the application field and working principle of MCP98243-BE/ST.

Application Field

MCP98243-BE/ST is a low-power temperature sensor that operates using the 2-Wire SMBus or I2C bus communication protocol. It is designed to work in high-temperature applications, with a wide temperature range of -40°C to +125°C. It is also designed to be highly accurate, with a resolution of 0.06°C and a high temperature accuracy of 0.5°C. The device also features low power consumption; it operates at operating current of 2uA, and a stand normally off current of 0.1uA. In addition, it also incorporates a NINT pin that can be used for setting an alert for an over-temperature condition.

The MCP98243-BE/ST can be used in a variety of applications, including power supplies, hard drives, server and storage racks, and automotive electronics. It can also be used for thermal management of industrial and consumer electronics, including processors, memories, displays, and other components.

Working Principle

The MCP98243-BE/ST is based on a diode temperature sensor that utilizes the NTC effect (semiconductor-based temperature coefficient). The NTC effect is an electrical phenomenon whereby the resistance of a semiconductor diode increases when the temperature decreases. The device uses two inputs, an NTC input and a VDS input, to measure the temperature. The VDS input is used to detect the voltage drop across the NTC, while the NTC input is used to detect the resistance of the NTC. These two inputs provide a very accurate measurement of temperature.

The device also incorporates an SMBus/I2C serial interface, which is used to communicate the temperature readings to the host processor. This allows the processor to monitor the temperature and take appropriate action if the temperature exceeds the specified limit. The device also features a NINT pin, which can be used to set an alert when the temperature rises above a specified threshold.

In addition to the SMBus/I2C communication interface, the MCP98243-BE/ST also features programmable temperature conversion times, an interrupt for temperature monitoring, and an open-drain output for overtemperature warning. The device also features an output enable pin, which allows the user to enable or disable the output.

Conclusion

The MCP98243-BE/ST is a temperature sensor that is designed to be highly accurate and reliable. It can be used in a variety of applications, and it incorporates several features that make it ideal for thermal management in industrial and consumer electronics. The device uses the 2-Wire SMBus or I2C bus communication protocol to communicate the temperature readings to the host processor, and it also features a NINT pin which can be used to set an alert when the temperature rises above a specified threshold. In addition, the device also features programmable temperature conversion times and an open-drain output for overtemperature warning.
