The MN13822STP PMIC or power management integrated circuit supervisor is a specialized tool designed to detect voltage excursions or overshoots, which can be very disruptive to the functioning of any electronic device. It is an affordable, small-footprint device with an integrated voltage supervisor that enables it to be used as a “vampire” protection circuit. By effectively managing and protecting against brown-out conditions, it ensures reliable reset control and power-on reset protection. It is a useful device for a variety of applications, specifically those related to reset protection.

The supervisor plays an essential role in regulating and managing voltage levels within the device by monitoring for abnormal conditions. By detecting changes in the input voltage and then reasserting a reset signal, it ensures that the system remains in a known state.

The MN13822STP can monitor up to four input voltages on a single device, making it an ideal set-up for anyone with multiple power supply sources. It has the ability to detect a wide array of conditions, including power supply spikes, undershoots, overshoots, and output pin problems, that would otherwise be difficult to detect. Additionally, the device can also detect a shift in the supply voltage of up to 150 mV during normal operation, allowing it to maintain a tight voltage regulation.

The MN13822STP is powered by a single 3-5V VDD input and has an output that can be configured for active high or active low reset. It is capable of supplying reset signals with a minimum pulse width of 10 μs, making it capable of detecting power-on reset conditions in microprocessor systems. It also has built-in slew rate control for ensuring that the reset signals remain accurate.

The MN13822STP can also be used to monitor the output voltage of a regulated power supply, providing protection from both overloading and/or underloading. This is its most common use, as an output voltage monitor for TFT LCDs or OLEDs, as well as for other types of industrial applications where accurate and reliable voltage monitoring is required.

Overall, the MN13822STP is a reliable and cost-effective solution for providing power monitoring and reset protection in a variety of application fields. It is easy to set up and its features enable it to provide accurate and reliable voltage monitoring in a variety of environments. With its wide range of features and a low power consumption, the MN13822STP is an excellent choice for anyone looking for power supply monitoring and reset protection in their device.
