PMIC - Supervisors are typically used in the electrical engineering and microelectronics industries and involve the design, development, manufacture and marketing of components for the management of power in electronic applications. The ADM709SAR is one such component, and it is typically used for reset management and system supervision in computer systems, embedded systems and communications systems among other applications.

The ADM709SAR is a low-voltage reset supervisory circuit module with a fixed supply voltage monitoring feature. It features an active-low reset output, an adjustable reset timeout range and an active-low push-pull reset output. It has integrated features including current sinking and current sourcing, open drain reset driving, adjustable reset threshold and power fail detection. Additionally, it has programmable reset timeouts and adjustability of threshold voltage to handle heavy supply loads.

The ADM709SAR works by monitoring the voltage of a power supply for fluctuations and supplying accurate reset signals at an adjustable threshold between 2.4V-4.63V. Whenever the detected voltage falls below the preset level, the reset output will become active and will remain so until the voltage recovers to within the safe operating range. It also provides a wide range of reset timings for different applications, ranging from 10 milliseconds to 10 seconds. It has low-current consumption and a wide reset-time range, making it suitable for different applications.

The ADM709SAR offers significant advantages over traditional reset sources that use relay links or transistor delays. It has an adjustable reset threshold that can be set to detect small shifts in the supply voltage, ensuring the system is protected from an indeterminate amount of fluctuations. It also has an active low push-pull output, allowing it to switch off power and reset the system at the right threshold levels. Additionally, the reset timeout feature enables it to reset the system after a certain period of time has elapsed.

The ADM709SAR is used in a wide range of applications and is particularly attractive in embedded systems, ultra-low-power systems, sensor networks and portable computers. Its low-current consumption and adjustable reset timeout capabilities make it suitable for use in activities such as remote meter reading, power line communications and inter-satellite communications. Its integrated voltage monitoring feature also makes it useful for data security applications.

In summary, the ADM709SAR is an advanced, low-voltage supervisory circulat module that has integrated features such as current sinking, current sourcing, and adjustable reset threshold. It is used in embedded systems, ultra-low-power systems, and portable computers, and also finds application in data security applications and remote meter reading. Additionally, its adjustable reset threshold and reset timeout features ensure the system is protected from any fluctuations in the supply voltage.
