The ADM693AARWZ-REEL belongs to the family of PMIC supervisory circuit components. It is used to provide detection and monitoring of power sources, system supervision and reset generation. The operating principle of the device involves monitoring and comparing the power supply voltage to an internal reference voltage.

The device consumes minimal power and requires external components that are not complex. Its standard operating voltage range is from 2.7V to 5.5V with low supply current of 500nA. The device has an internal reset delay of 10ms which enables it to provide a reset signal during power-up or power-down. In addition, it provides an active-high reset output which is set high by default; however, its output can be pulled low by the user until the reset condition is removed.

It features two independent comparator inputs with adjustable thresholds. This allows the user to readily monitor two different power supplies simultaneously. Moreover, it contains an integrated watchdog timer with a timeout period of up to 14 seconds. This timer can be used to detect system problems and issue a reset appropriately.

The ADM693AARWZ-REEL is an ideal device for applications in consumer electronics, such as portable computers, tablets and smartphones, that are powered by multiple voltage sources. It can also be used to monitor a variety of other applications including embedded systems and automotive systems. The device offers excellent protection against system failures and provides a reliable reset signal.

To sum up, the ADM693AARWZ-REEL is a highly compact and efficient PMIC supervisor circuit component. It provides reliable monitoring of two different power supplies, an integrated watchdog timer with adjustable timeout period and manual reset capability. It supports a standard operating voltage range from 2.7V to 5.5V, it has a low supply current of 500nA and features a reset delay of 10ms. These features make it well suited for applications in consumer electronics, embedded systems and automotive systems.
