PMIC supervisors, such as the ADM1813-5ARTZ-RL, are integrated circuits dedicated to monitoring power rails in a variety of applications. These supervisors can detect fault conditions on the power rails and proactively act to protect the system. This application note will discuss the general application field and working principle of the ADM1813-5ARTZ-RL.

Application Field

The ADM1813-5ARTZ-RL is a dual voltage supervisor IC, with a protected input voltage range of 2.5V to 5.5V. It is designed to be used in a variety of applications, including computer systems, automotive electronics, communication systems, power supplies, and embedded systems. In each application, the supervisor can be used to detect when the power rail reaches a critical fault voltage and take proactive action to protect the system.

Working Principle

The ADM1813-5ARTZ-RL has two integrated comparator circuits. Each comparator monitors a separate voltage level and has independent trip points. When the input voltage reaches the lower trip point, the supervisor will generate an alarm signal. If the input voltage reaches the higher trip point, the supervisor will shut down the system and reset. The supervisor also includes a watchdog timer, which can be used to issue a system reset if the processor is stuck or fails to respond.

The supervisor also includes integrated power-on reset and power-down reset circuits. The power-on reset circuit ensures that the system starts up reliably, while the power-down reset circuit ensures that the system shuts down safely. The supervisor also includes a protected output voltage level feature that allows it to monitor the output voltage level and make sure it stays within a safe range.

The ADM1813-5ARTZ-RL also features a wide range of features designed to make it easy to use. It includes an open-drain output pin, a selectable comparator response time, and an adjustable trip point. It also supports adjustable hysteresis and software programmable delay time. In addition, there is also an integrated serial interface with I2C support.

Conclusion

The ADM1813-5ARTZ-RL is a powerful supervisor IC designed for use in a range of applications. It can detect fault conditions on the power rails and proactively act to protect the system. It includes a wide range of features, including open-drain outputs, adjustable comparator response times, adjustable trip points, adjustable hysteresis, and software programmable delays. In addition, it supports an integrated I2C serial interface for easy communication. With these features, the ADM1813-5ARTZ-RL is an ideal supervisor IC for a variety of applications.
