PMIC - Supervisors are a broad class of power management integrated circuits that monitor, control, and prevent electrical abnormalities, thus protecting a system from damage due to excessive current, undervoltage, or overtemperature conditions. The ADM1816-R22ARTZ-RL is an example of one such supervisor device. It is an adjustable, low-threshold voltage supervisor solution that is ideal for a variety of applications. This article will discuss the application field and working principle of the ADM1816-R22ARTZ-RL.

Application Fields

The ADM1816-R22ARTZ-RL is ideal for a variety of applications across multiple industries, such as automotive, industrial, aerospace, military and medical. As a low-threshold voltage supervisor, its primary benefit is that it is able to detect voltage levels that are lower than ordinary supervisor devices. This makes it a great device for application with low-voltage requirements, such as battery-powered applications. Other possible applications include motor control, robotics, self-monitoring and control systems, and special communication interface/switching applications.

The ADM1816-R22ARTZ-RL can also be used as a reset generator for microprocessors. It is designed to detect voltage levels below the reset threshold level, keeping the logic level high so that it remains stable. In this way, a microprocessor can be reset, protecting the system against computer and instability.

Working Principle

The ADM1816-R22ARTZ-RL is a supervised circuit that operates on the principle of monitoring the input voltage of power supplies and detecting when the supplied voltage is lower than a predetermined threshold voltage. When this occurs, the output is then changed and a reset signal is generated. The device is adjustable, and the adjustable threshold level can be set using an external resistor.

The reset function is based on the design of two comparators that are connected in series and work together to detect the low voltage threshold level. One comparator is designed to detect inputs that are below the adjustable threshold level and the other is designed to detect inputs that exceed the adjustable threshold level. When the first comparator detects the low voltage threshold level, it triggers a reset signal and the output is reset.

Once the reset signal has been generated, the ADM1816-R22ARTZ-RL is able to hold the reset until the voltage level is restored to a level above the adjustable threshold voltage. This allows the device to function in both an active and a passive reset state.

In addition to its adjustable threshold voltage, the ADM1816-R22ARTZ-RL also features several other features that make it p erfect for a variety of applications. It is tolerant to reverse supply, making it ideal for automotive applications and applications that require reverse polarity protection. In addition, it has a wide operating temperature, making it suitable for applications in extreme environmental conditions. Moreover, it has an 8-kV ESD rating, making it suitable for use in environments where electrostatic discharge could be a concern.

The ADM1816-R22ARTZ-RL is a great choice for applications that require low-voltage monitoring, reset generation and protection from electrostatic discharge. Its adjustable threshold voltage, reverse polarity protection, wide operating temperature and 8-kV ESD rating make it an ideal choice for a variety of applications, from automotive to aerospace and beyond.
