MIC6315-30D2U

Power Management Integrated Circuit (PMIC) supervisors, also known as power management/supervisory circuits or voltage supervisors, are integrated circuits that monitor the power supply voltage level in electronic circuits. One of the most popular kinds of PMIC supervisor is the MIC6315-30D2U, a Hi-side Low-side Power-Fail Supervisor used to monitor the power supply voltage in a variety of applications, particularly those running on the Windows operating system. This article will discuss the application field and working principle of the MIC6315-30D2U.

Application Field

The MIC6315-30D2U has a wide variety of applications, particularly those that require a reliable power supply monitoring system. In particular, it is commonly used in data centers and server boards that use the Windows operating system. The MIC6315-30D2U is also used in industrial control systems, computer peripherals, and automotive applications, where it is used for the monitoring and protection of voltage rails in order to independently power control circuits. Additionally, the MIC6315-30D2U is used in communications equipment, such as mobile phones, where it is used to monitor battery voltage in order to ensure that the battery does not become overcharged or drained.

Working Principle

The MIC6315-30D2U is an integrated circuit (IC) which monitors the power supply voltage and provides an output signal, when there is a deviation from the normal, pre-defined voltage level. The main function of the MIC6315-30D2U is to monitor the power supply voltage and provide an output signal when the voltage drops below or exceeds a pre-defined level. The MIC6315-30D2U operates by sensing the supply voltage on one of its two “sensing pins”, and compares this voltage with a reference voltage which is determined by the integrated circuit design. If the voltage on the sensing pin is lower than the reference voltage, then the MIC6315-30D2U will drive an output signal which signals the power failure. Similarly, if the voltage on the sensing pin is higher than the reference voltage, then the MIC6315-30D2U will drive an output signal which signals an over-voltage event. The output signal of the MIC6315-30D2U can then be used to control an external circuit, such as a shutdown circuit or alarm which can notify the user that a voltage failure has occurred.

Conclusion

The MIC6315-30D2U is a Hi-side Low-side Power-Fail Supervisor used to monitor the power supply voltage in a variety of applications. It is commonly used in data centers and server boards that use the Windows Operating System, as well as in industrial control systems, computer peripherals, automotive applications, and communications equipment, such as mobile phones. The MIC6315-30D2U operates by sensing the supply voltage on one of its two “sensing pins”, and provides an output when the voltage drops below or exceeds a pre-defined level. The output of the MIC6315-30D2U can then be used to control an external circuit which can notify the user that a voltage failure has occurred.
