Application Fields

The M1382CP is suitable for all kinds of control, power supply, and voltage monitoring applications. It is designed to be used in embedded systems control as well as power supply for secondary protection circuits. It can also be used in automotive and home appliances, communication systems and other equipment requiring voltage supervision.

The M1382CP can be used in applications where the over voltage or temperature needs to be monitored, such as in computer main boards or other system control. It can also be used for applications where high accuracy, low power consumption, and superior immunity to electrical noise are key factors.

Working Principle

The MN1382CP utilizes an external reference voltage (VREF) to set the reset voltage (VRESET). As the input voltage (VIN) reaches the reset voltage level, the falling edge of the reference voltage triggers an output reset. This output reset can also be triggered automatically by built-in over-voltage/over-temperature protection circuits.

The MN1382CP uses an internal delay counter to accurately measure the reset time, and then delay the reset pulse till tVilin reaches the specified level. The timing of the internal delay count is adjustable and programmable, so it can be used for applications with different timer parameters. The overvoltage and temperature protection circuits can be used independently or together depending on the application.

The MN1382CP can be used in a multitude of applications as it offers high accuracy, low power consumption and high immunity to electrical noise. Its integrated reset circuit protects the system from over-voltage and over-temperature conditions, while the internal delay count and adjustable timer parameters provide a more flexible approach to voltage supervision. The M1382CP is an ideal choice for various control, power supply and voltage monitoring applications.
