PMIC or Power Management Integrated Circuits are numerous types of integrated circuits integrated in a single piece of Silicon and are primarily used for controlled power management in various applications. A type of PMIC, supervisors, serve as a monitoring system. ADM811-3TART REEL7 is a particularly miniaturized supervisor IC, which not only have the functionality of a traditional supervisor, but also have extra features such as the low input voltage range, wide range operation and low power consumption.

The ADM811-3TART REEL7 is mainly used in applications where power control is required. These include portable and other systems, as well as medical, industrial, automotive and communications applications. It is designed to monitor and protect the main power supply, providing the system with fail-safe performance when the input voltage drops below the set threshold, or goes above the set threshold. It can also be used as a protection feature against reverse-voltage and overvoltage conditions.

Working Principle

The working principle of the ADM811-3TART REEL7 is a two-stage voltage monitoring system. In the first step, a signal comes in from the voltage regulator, informing the supervisor of the current input voltage of the circuit. If the monitored voltage is within the prescribed range, the supervisor will continue to deliver power to the system and operate normally till the input voltage changes. However, if the monitored voltage level exceeds or falls below the set thresholds, the supervisor signals the peripheral circuitry to isolate the power supply and eliminate it from the system.

The logic input thresholds of the supervisor are adjustable, allowing the system design to adjust the sensitivity to reach the required level of protection. As such, the ADM811-3TART REEL7 is suitable for keeping high power application safe from sudden voltage changes that occur when there are hardware or software glitches. Additionally, if a third part device is connected in its circuit, the supervisor will send an output signal to trigger the device in the event of an overvoltage or undervoltage situation.

Feature

The ADM811-3TART REEL7 also comes packed with a few other handy features, such as an adjustable reset threshold, wide operating range and a low input voltage range. With its adjustable reset threshold, the supervisor can be adjusted to an appropriate level to help provide an accurate indication of when the system is operating safely, as well as how much power is consumed by the system. Additionally, the wide operating range is useful for applications that operate with varying input voltages. Finally, the low input voltage range allows for a more efficient use of energy, which can help reduce energy costs.

Conclusion

In conclusion, the ADM811-3TART REEL7 supervisor IC is an effective way to ensure efficient and safe operation in many types of applications. With its two-stage voltage monitoring system, adjustable reset threshold, wide operating range, and low input voltage range, the supervisor is reliable in ensuring that the system is provided with fail-safe performance during voltage irregularities. This makes it ideal for use in various applications that require power control capabilities.
