PMIC - Supervisors are a type of integrated circuit (IC) used to manage power and reduce power consumption. The ADM698SQ is a low-power, low-quiescent current supervisor designed to monitor and protect against overvoltage and undervoltage readings on power supply output lines. It is a poly phase supervisor with voltage range and overvoltage/undervoltage protection that can be configured to meet the requirements of different applications.

The ADM698SQ has an integrated high-speed comparator and voltage supervisor that are capable of monitoring positive and negative input voltages ranging from 0.1V to 28V. The part operates in normal mode up to a maximum voltage of 33V, and features a maximum quiescent current of 0.01μA with a wide temperature range of -40C to +85C. In addition, it includes a manual reset switch, a CMOS/TTL compatible output, and an open-drain status output flag.

The main feature of the ADM698SQ is its wide input range which makes it ideal for use in small, medium, and large systems. The supervisor will alert the host system in the event of an overvoltage or undervoltage condition, allowing the host system to take timely corrective measures. In addition, the part provides Hysteresis, Low voltage reset delay, and manual reset functions which enable the user to adjust the device’s settings according to its application.

The ADM698SQ is most commonly used in applications such as computing equipment, power supply systems, and battery backup systems. In computing equipment, the supervisor may be used to monitor the supply voltage for the CPU, GPU, and system memory. In power supply systems, the device can detect and alert when the system supply voltage exceeds a preset threshold. Finally, in battery backup systems, the ADM698SQ can protect against over-discharge situations by detecting and alerting when the battery voltage drops lower than a preset threshold.

The working principle of the ADM698SQ is simple. It monitors the input voltage and will compare the input voltage against a pre-determined threshold value. If the input voltage is higher than the threshold value, the device will alert the host system. If the input voltage is lower than the threshold value, the device will alert the host system. The device is also capable of providing a manual reset function which allows the user to reset the supervisor.

The ADM698SQ is an ideal solution for systems that require reliable overvoltage and undervoltage protection. Its wide input range and low quiescent current make it ideally suited for a variety of applications, particularly those in the computing, power supply, and battery backup industries. The part is also equipped with an easy-to-use manual reset switch and a CMOS/TTL compatible output flag, allowing users to adjust its settings quickly and seamlessly.
