MN1382PP is a monitoring circuit which is designed to provide an accurate supply voltage control for digital circuits and to protect the system from any power supply problem. It is a subset of Supervisors, which falls under the category of PMIC (Power Managed Integrated Circuitry). The main purpose of the MN1382PP is to monitor the main power supply for over-voltage, over-current and under-voltage. It works around a preset reference voltage and will provide a digital output signal when the power supply exceeds a given threshold.

The MN1382PP is a dual-phase power supply supervisor, having one set of voltages detection input with two different output levels. The input voltage’s reference level is set at the two voltage levels, and when either of the levels is exceeded, the output signal is activated. The two outputs consist of an open-drain output and an active-high output. The active-high output is connected to the logic control circuit, while the open-drain output is connected to the power control circuit.

The application of MN1382PP includes, but is not limited to, DC to DC power supply in the range of 4 V to 15 V, digital power supplies, motherboard power supply, digital power supply design and power supply control. The on-chip comparator of the MN1382PP can operate from a supply voltage ranging from a minimum of 2.0 V to a maximum of 18.0 V. It is designed to be used in both low and high voltage applications.

The working principle of the MN1382PP is really simple. It is designed to monitor the main power supply for over-voltage, over-current and under-voltage. It works around a preset reference voltage and will provide a digital output signal when the power supply exceeds a given threshold. The circuit includes two voltage detection inputs and an output. The voltage monitoring is done by a comparator circuit which compares the input voltage to a preset reference voltage. When the input voltage is greater or less than the reference voltage, the output of the comparator is activated and the corresponding output signal is generated.

The output signal is then used to disable the power supply or to signal the circuit controller to take some form of corrective action. For example, if the output signal is high, the power supply could be disabled, and the circuit controller could be instructed to shut down the system. Similarly, if the output signal is low, the circuit controller could be instructed to take corrective action such as reducing the power supply voltage.

The main advantage of using the MN1382PP power supply supervisor is that it provides an efficient and accurate monitoring of the power supply for over-voltage, under-voltage and over-current. It is also a cost-effective solution for controlling the power supply and for providing a reliable and accurate output signal. The MN1382PP is a versatile power supply supervisor that can be used in a wide range of applications and is designed to withstand a wide range of input and output conditions.
