The MN13822LP is a Single Channel Supervisor developed by Panasonic. It is classified as a PMIC-Supervisor, and it is designed to provide circuit protection for power management applications. The supervisor is suitable for use in many applications, such as motor drive systems, automotive airbags, digital power supplies, and power supplies for consumer electronics and telecommunications systems. In addition, the MN13822LP is an ideal solution for ultra-low power applications, providing reliable protection with very low power consumption.

The MN13822LP is a single channel supervisor with a protection voltage of up to 25V. The internal protection circuit provides fast response time and reliable protection from over-voltage and under-voltage conditions. The integrated bias voltage generation circuit allows stable operation of the device in a wide range of supply voltages. The MN13822LP also provides a reset signal, which can be used to signal the occurrence of an over-voltage or under-voltage condition. The reset signal can be configured as an open-drain signal or a push-pull signal.

The MN13822LP is designed to provide silent fault protection in many applications, including motor drive systems, automotive airbags, digital power supplies, and power supplies for consumer electronics and telecommunications systems. The MN13822LP operates in two different modes: active mode and standby mode. The obvious distinction between the active mode and the standby mode is that in the active mode the MN13822LP is actively monitoring for any over-voltage or under-voltage conditions. Whereas in the standby mode no monitoring is performed, however, the reset signal is still available in case an over-voltage or under-voltage condition occurs.

The working principle of the MN13822LP is simple. The device incorporates an operational amplifier, a voltage reference and a voltage divider connected together to form a comparator. The operational amplifier is used to compare the output voltage with the reference voltage from the internal voltage reference. If the output voltage rises above or falls below the set threshold, the amplifier’s output will trigger the reset signal, which can then be used to reset the system or signal an alarm.

In conclusion, the MN13822LP is a PMIC-Supervisor designed for use in a wide range of applications. It provides stable operation with very low power consumption and fast response time. It operates in both active and standby modes and can provide a reset signal in the event of an over-voltage or under-voltage condition. The working principle of the MN13822LP is based on a simple comparator circuit which compares the output voltage with the reference voltage and triggers the reset signal if necessary.
