MCP98244T-BE/MNY Integrated Circuits (ICs)

The MCP98244T-BE/MNY is a multifunction power management IC (PMIC) from Microchip technology with thermal management capabilities. It offers a wide range of features, including voltage and current monitoring, as well as overvoltage and overcurrent protection. Furthermore, it has a thermal diode for temperature sensing, and is suitable for applications including data centers and central office equipment, as well as any other application where an efficient and cost effective PMIC is required.

The MCP98244T-BE/MNY chip offers an on-board temperature sensor, allowing for the temperature sensing of components in the given application. This sensor is a thermistor, which has a temperature resistance-to-voltage characteristic. To be able to adjust the sensitivity of the thermistor, the user can modify the VTH, a reference voltage that sets the trip point to which the thermistor is calibrated. VTH is adjustable from 0.15V to 5.5V, with a typical range of 0.15V to 1.4V.

The MCP98244T-BE/MNY is capable of monitoring both temperature and voltage. The chip has two comparators with different thresholds. The first comparator is used to monitor the temperature, at the same time the segmented level (SGC, or segmented level comparator) is used to monitor the voltage. The SGC generates a signal when either the voltage is too low or too high, according to a user adjustable threshold.

In addition, the chip has a wide variety of voltage and current protection features, to ensure that any component within the circuit is protected from damage. Overcurrent and overvoltage detection include the ability to adjust the trip point of the comparators and to set the trip time to 1ms or 2ms, depending on the application. It also offers a variety of other features, such as hysteresis, slew rate and others.

Thermal protection is one of the most important aspects of any system, since it ensures that a component of the system is not subjected to extreme heat. Thermal protection is especially important in high power systems, as too much heat can cause failure of components. With the MCP98244T-BE/MNY, thermal protection is provided through the on-board thermistor, which can be adjusted to operate at different levels for different temperature ranges. This allows for accurate thermal protection for any given application.

In summary, the MCP98244T-BE/MNY is a multifunction power management IC with thermal management capabilities, suitable for a variety of applications. It offers a wide range of features, including voltage and current monitoring, overvoltage and overcurrent protection, and temperature sensing. Furthermore, it has an adjustable VTH, allowing the user to adjust the trip point of the thermistor. In addition, the chip provides a variety of other features, including hysteresis, slew rate and other protection features, allowing for an efficient and cost effective thermal management solution.
