ADM809MAKS-REEL7

PMIC - Supervisors

A PMIC - Supervisors is a device that monitors the operating parameters of an electronic system to ensure it always remains within safe limits. ADM809MAKS-REEL7 is one of the most widely used types of PMIC supervisors.

Application Field

The ADM809MAKS-REEL7 is a low-cost, low-power CMOS supervisor with the following features: highly optimized reset delay time and reset threshold accuracy, wide operating voltage range, low quiescent current, multiple reset timeout settings, integrated overtemperature protection and separate power on reset and power supply monitoring, and external programmable reset timeout. It can be used for many popular embedded applications, such as power supplies and microcontrollers. In addition, it also has proven performance in automotive, medical, industrial, and other critical applications.

Working Principle

The ADM809MAKS-REEL7 is based on a CMOS comparator, microprocessor, and reset control logic. The comparator monitors the voltage of the electronic system, and distinguishes when the voltage is outside of a set of predetermined values. Once the comparator detects a fault, it triggers the reset control logic, which resets the system. This resetting can occur either automatically or on manually triggered reset (externally or internally). The reset control logic also has a separate power on reset (POR) circuit, which allows the device to reset the system when its power is momentarily removed and then reapplied.

The ADM809MAKS-REEL7 also has power supply monitoring functions that allow it to monitor the system\'s power supply for faults and take appropriate corrective action. The power supply monitoring can also be used to reset the system when the voltage drops too low or becomes too high. Additionally, the ADM809MAKS-REEL7 has an integrated overtemperature protection function, which can be used to detect when the system is too hot and immediately shut it down to prevent damage.

Finally, the ADM809MAKS-REEL7 has a programmable reset timeout function, which allows the device to reset the system after a certain amount of time if a fault is not detected. This ensures that the system remains in a safe state even if the fault is not detected immediately.

Conclusion

The ADM809MAKS-REEL7 is an ideal choice for a wide range of embedded application due to its optimized reset delay time, reset threshold accuracy, wide operating voltage range, low quiescent current, multiple reset timeout settings, and power supply monitoring. The device also has an integrated overtemperature protection function and programmable reset timeout capabilities, making it an effective and dependable tool for ensuring system safety.
