Power management integrated circuits (PMICs) are semiconductor devices that are specially designed to manage the power supplied to various electronic devices. A power supervisor, a type of integrated device, is used to identify and monitor the power supply-related problems in electronic circuits. One of the most popular power supervisors used in a variety of applications is the ADM690SQ. In this article, we will discuss the application field and working principle of the ADM690SQ power supervisor.

Application Field of ADM690SQ Power Supervisor

The ADM690SQ power supervisor IC is a robust IC with a wide range of applications. It is typically used in computers, where it is used to monitor and manage power supply related operations of the motherboard and other components. It can also be used in other PCBs such as telecommunications, automotive electronics, consumer electronics and medical instrumentation.

The ADM690SQ is especially popular in computer motherboards, where it monitors the power supply. It is used to monitor the voltages of different components in the motherboard, such as the CPU and other components. When the voltage of a component exceeds the maximum level or falls below the minimum level, the ADM690SQ can cut off the power supply, protecting the component from potential damage. It can also send out warning messages.

The ADM690SQ is also used in other applications such as automotive electronics and consumer electronics. For example, it can be used to detect overvoltage and undervoltage conditions in automotive systems, and it can also be used to detect faults in power supplies for consumer electronics.

Working Principle of ADM690SQ Power Supervisor

The ADM690SQ power supervisor IC is a low-power CMOS-based device with a wide operating temperature range. It contains a micropower voltage supervisor, a watchdog timer and a power-on reset circuit. The watchdog timer is designed to detect any malfunction in the system and reset it, while the power-on reset circuit is used to detect and reset any faults due to power fluctuations.

The voltage supervisor module of the ADM690SQ compares the supply voltage with two fixed thresholds - an undervoltage threshold and an overvoltage threshold. When the voltage level exceeds or drops below the pre-set thresholds, the voltage supervisor sends out a signal that triggers the watchdog timer. The watchdog timer then sends out a reset signal to the power-on reset circuit, which then issues a reset signal to the corresponding component.

The ADM690SQ power supervisor also contains a digital/analog converter, which is used to monitor the analog input and convert it into digital signals. This allows the IC to monitor temperature, humidity or other conditions and send out a warning signal when the readings exceed the pre-set thresholds.

The ADM690SQ is an extremely robust IC with a wide range of applications. It is used to detect faults and reset components to prevent damage caused by power fluctuations, and it is also used to detect temperature and humidity conditions. It is a reliable device capable of providing great protection to the various electronic components.
