The MN13821NP is a device from the PMIC - Supervisors class. This device is a 5-bit supervisory circuit which is used for both system reset monitoring and voltage monitoring. The MN13821NP offers circuit designers flexibility in their choice of reset timing, allowing them to design systems with longer hold-up times, lower power consumption, and higher levels of system stability. The MN13821NP also provides a low-power reset signal and programmable reset output polarity.

The MN13821NP is designed to monitor power supply and/or processor activity in a variety of digital systems. This device can be used to reset microprocessors and memory devices, as well as other integrated circuits. It can also be used to monitor battery voltage levels in mobile devices and other low-power systems. The device is highly integrated, offering 5-bit reset and voltage monitoring on the same device with a minimum of external components.

The MN13821NP is programmable via configuration resistors. These resistors allow the user to set the trip voltage at which the reset signal is generated, as well as the degree of hysteresis. This feature gives the designer the flexibility to configure the device to suit their application.

The MN13821NP is ideally suited for battery-backed systems and other applications where a low power reset signal is needed. Its small footprint, low power consumption and wide voltage range make it a good choice for portable products, such as laptop and mobile applications. The device also features internal logic designed to prevent false reset trips due to momentary power outages.

The reset output of the MN13821NP is an open collector type. This allows the user to control the reset output polarity via the configuration resistors. The reset polarity can be inverted, with an active low reset, or non-inverted, with an active high reset. This allows the user to easily adapt the device to their circuit design.

In addition to its reset and voltage monitoring capabilities, the MN13821NP also features an internal voltage reference, temperature sensor, and temperature-compensated reset signal. The temperature sensor allows the device to compensate for temperature-related reset outliers, making the reset signal more reliable over a wide range of temperatures. The voltage reference allows for accurate voltage monitoring, even under varying environmental conditions.

The MN13821NP is a versatile, low-power supervisory circuit that can be used in a variety of applications. Its integrated features, such as the voltage reference, temperature sensor, and programmable reset output polarity, make it a reliable choice for reset and voltage monitoring in a wide range of systems.
