The MN13821SCP is a specialized PMIC - Supervisors device, which is designed to protect electronic systems from malfunction and damage while providing accurate voltage regulation and monitoring. The device integrates a wide variety of features such as voltage monitoring, adjustable voltage threshold, power-on reset, and filter capacitors. The MN13821SCP is essential for improving the reliability of complex electronic systems, especially those that require accurate voltage monitoring and protection.

The MN13821SCP is suitable for a variety of applications, including system power management, peripheral power management, over-voltage/current protection, system backup, and power on reset. It is an ideal choice for applications that require a highly reliable voltage regulation and protection solution. With a low operating voltage, up to 75μA quiescent current, and adjustable voltage thresholds, the MN13821SCP is a suitable choice for systems that require high performance, low power, and reliability.

The MN13821SCP works by monitoring its inputs for any deviations from the set values. It then either pulls the reset pin low or sets an active-low output indicating a fault condition. This way, the device enables power backup as well as allows system reset when an over-voltage/over-current condition occurs. Additionally, it has static and dynamic low-power standby modes (mode 2 and mode 3) and a “laag” output to indicate a low-voltage condition.

In order to ensure an accurate voltage monitoring and protection, the MN13821SCP incorporates a dedicated volt-second filter circuit. This filter circuit uses a combination of a voltage reference and a resistor divider network to ensure +/-±1% accuracy over a wide temperature range. This circuit also provides an adjustable voltage threshold so that the device can be configured to detect over-voltage/current conditions at any voltage within its 5V to 24V operating range.

The MN13821SCP features a large variety of protection and control features. These include an adjustable reset time, unprovided power management, power-on reset delay time, and an adjustable input voltage hysteresis. Additionally, the device incorporates two power-on reset circuits that provide two different levels of protection. The first circuit monitors input voltages and provides a short-term reset feature, while the second circuit provides a longer term reset feature.

All in all, the MN13821SCP is an excellent choice for applications that require a highly reliable voltage regulation and protection solution. It’s wide operating range and adjustable voltage thresholds make it suitable for a variety of applications, and its dedicated filter circuit ensures accurate voltage monitoring and protection. Moreover, its two power-on reset circuits provide two levels of protection, making it a great choice for any system requiring a robust power management solution.
