The ADM699ARZ is a supervisory PMIC (Power Management Integrated Circuit) designed to monitor and protect the system from excessive supply voltage levels, current overloads, and brown-out conditions.

The device consists of a reset controller with an integrated watchdog timer that can be easily programmed over a wide range of time. It also features an analog temperature sensor as well as an adjustable-threshold comparator with an integrated overvoltage monitor with active-low watchdog output.

The ADM699ARZ has a wide operating voltage range of 2.7V to 5.25V and is ideal for a variety of applications such as microprocessors, mobile device, consumer electronics, and automotive applications.

The device can be configured to generate a hardware reset pulse when the voltage exceeds the defined threshold. The hardware reset pulse can be programmed to be long enough to restore the system to a stable operating condition. In addition, the device can be used to detect current overloads and brown-out conditions, thus protecting the system from catastrophic failures due to supply voltage droops or disruption. The ADM699ARZ can also monitor battery voltage level and detect overvoltage conditions.

The device features an integrated watchdog timer that can be set to timeout within a wide range of 32.768ms to 2.56s, enabling it to detect system lockups and initiate corrective action. The watchdog timer can be enabled or disabled via a software command.

The analog temperature sensor ensures that the system will not be exposed to high temperatures, which could cause system instability. When the temperature exceeds the defined threshold, the device will generate an active-low reset signal to restore the system to a safe operating temperature.

The adjustable-threshold comparator integrated in the device can be used to detect an open or short circuit condition on a signal line. In addition, the device also has an overvoltage monitor with an active-low reset output which can be used to monitor and protect the system from excessive supply voltage levels.

Overall, the ADM699ARZ is a highly integrated, feature-rich supervisory PMIC which offers reliable protection against excessive supply voltage levels, current overloads, and brown-out conditions. With its adjustable-threshold comparator, analog temperature sensor, and integrated watchdog timer, the ADM699ARZ is an ideal solution for a variety of applications such as microprocessors, mobile devices, consumer electronics, and automotive applications.
