The ADM691AARNZ is a type of supervisory IC (Integrated Circuit) that’s designed to protect electronic equipment from power-related faults. With its multi-functional capabilities, the ADM691AARNZ supervisory IC plays an important role in power management and battery management applications. This article will explore the application field and working principle of the ADM691AARNZ.

Application field

The ADM691AARNZ supervisor IC offers excellent stability and accuracy to protect micro-computers, micro-controllers, and other applications operating in an environmental range of -40°C to +85°C. It contains features such as low quiescent current, programmable voltage monitor, manual reset, brown out, power-on reset, and adjustable reset timeout. The features integrated in this supervisor IC allow it to provide robust protection in power management and battery management circuits.

The ADM691AARNZ can also be used in HVAC (Heating, Ventilation, and Air Conditioning) systems, motor controllers, robotic systems, communications equipment, portable medical devices, automotive systems and other applications where power supply monitoring and protection are required.

Working Principle

The working principle of the ADM691AARNZ is based on three reset output logic signals. These signals interact with the input logic signals and the power supply reference voltage to monitor the condition of the power and fault conditions.

When the power supply voltage is greater than the power supply reference voltage, the ADM691AARNZ enables the reset output signal, thus allowing the device to reset itself. On the other hand, when the power supply voltage drops below the power supply reference voltage, the ADM691AARNZ generates a reset signal, disabling the device and protecting it from further damage. The ADM691AARNZ also provides an adjustable reset timeout period, which determines how long the device will remain in a reset state before resetting itself.

The ADM691AARNZ supervisor IC also contains a brown-out detector, which monitors the power supply voltage and detects if it drops below a pre-defined level. If a brown-out is detected, the ADM691AARNZ will trigger an alarm and generate a reset signal to reset the system. By cutting off the power supply to the protected circuit, the ADM691AARNZ prevents further damage and ensures the reliability of the system.

The ADM691AARNZ also contains a manual reset input, which can be used to perform a hardware reset of the system. The manual reset input can be used to trigger a reset signal under certain circumstances, such as when a technician requires a safe shutdown of the system.

Conclusion

The ADM691AARNZ supervisory IC offers an efficient and reliable solution for power management and battery management applications. With its comprehensive set of features, the ADM691AARNZ can be used to protect any electronic equipment from a power failure or other power-related fault. This article has explored the application of the ADM691AARNZ, as well as its working principle.
