PMIC – Supervisors are a type of trusted electronic device which provides monitoring, control, and protection for systems in motion. The MN13821STP is a single-channel PMIC supervisor which provides protection for circuits in motion. It is designed for use in motor drives, vehicles, industrial, home appliance, and military/aerospace applications. Its main function is to monitor and control the current, voltage, and temperature of its load.

The MN13821STP consists of a voltage sensing block, a voltage comparator, and two programmable delay timers. The voltage sensing block is responsible for monitoring the supply voltage of the load. The voltage comparator is used to compare the sensed voltage to the set thresholds, and then provide an output signal according to the comparison result. The two delay timers are also provided, which can be programmed to fit various requirements in terms of time delays.

In terms of system protection, the MN13821STP provides current-limit and overvoltage protection. The current-limit protection feature monitors the current flowing in the load, and will shut off the load if the current exceeds the predetermined levels. The overvoltage protection feature will also shut off the load if the voltage rises above specified levels.

The MN13821STP also provides temperature monitoring and control. It has an internal temperature sensor which can be used to detect the temperature of the load and provide an output signal when the temperature rises above its set threshold. The thermal protection feature can be used to shut off the load if the temperature remains high for a period of time.

The MN13821STP works in conjunction with the load circuitry to ensure that the system is working properly. The internal voltage sensing block and comparator can detect when the supply voltage is too high or low, and will shut off the load before any damage is done. The delay timers are used to ensure that the load is shut off only after a certain delay, allowing the user to reset the system if necessary. The current-limit and overvoltage protection features also provide added protection by cutting off the supply before any permanent damage is done.

The MN13821STP is an ideal choice for protecting circuits in motion. Its internal sensors and components provide reliable protection within a wide voltage range, and its various features offer flexibility in terms of functionality and system protection. Its small package size and low cost make it attractive for motor drives, vehicles, industrial, home appliance, and military/aerospace applications.
