Introduction

PMICs or Power Management Integrated Circuits are semiconductor devices used in electronics applications to regulate the power supply to a given system. They are typically found in digital devices, such as mobile phones, tablets, and computers. PMICs help maintain the power supply by providing a range of features that enable the device to adjust its power consumption in response to changing conditions. One such PMIC is the ADM695ANZ, a power supervisor IC from Analog Devices Inc. It is designed to monitor, detect, and respond to power anomalies in applications ranging from industrial automation, medical equipment, military, and aerospace.

Features and Benefits

The ADM695ANZ is a robust and reliable power supervisor IC that offers a number of features for improved system protections.It offers an adjustable reset timeout that can be used to customize the reset period in order to better protect the system. It also has adjustable under-voltage monitoring thresholds that can be programmed to sense a wide range of input voltage levels.The power supervisor IC offers a wide range of reset timeout values, ranging from 100 ms to 85 s, and provides additional flexibility with an adjustable hysteresis or reset hysteresis feature, which allows the user to set a percentage of the reset voltage to the maximum voltage the device can detect.The ADM695ANZ is designed to operate at a wide range of operating temperatures, and it is housing in a small package size and low profile, making it suitable for space-constrained applications.In addition, the IC has an integrated system and power on reset (SPOR) controller, which provides a reset signal that can be used for logic resetting after a power-on event.

Applications

The ADM695ANZ is suitable for industrial automation, medical equipment, military, and aerospace, as well as consumer electronics, automotive, and renewable energy systems. These applications typically require reliable and accurate protection from voltage dropouts, overvoltage, and brown-outs.The power supervisor IC is also well-suited for use in medium-power digital systems, as it can monitor and regulate the power supply to ensure that the system operates as expected. The ADM695ANZ can be used in communications systems and other digital applications that require reliable power supply monitoring and accurate power regulation.

Working Principle

The ADM695ANZ is designed and engineered with a dual-channel flip-flop arrangement that allows the device to detect and respond to multiple power anomalies in order to ensure reliable system operation. One of these channels is used to detect and respond to AC power fault signals, while the other channel can detect and respond to a variety of DC fault signals including brown-outs, over-voltage, and under-voltage conditions.The ADM695ANZ is equipped with a voltage threshold detector that senses the voltage levels at the IC’s input and, in response, generates an appropriate output signal. If a fault condition is detected, such as an over-voltage, the power supervisor IC will trigger the reset time-out (RTO) flip-flop, which delays the reset signal for a predetermined period of time before interrupting the power supply to the system.Once the reset time-out is complete, the ADM695ANZ will then generate a reset signal that would cause the system to reset to its original state.

Conclusion

The ADM695ANZ is a reliable power supervisor IC that is designed to monitor, detect, and respond to power anomalies in a variety of digital applications. Its dual-channel flip-flop arrangement allows it to detect and respond to both AC and DC power faults, and its adjustable threshold and reset timeout values make it suitable for a wide range of industrial and consumer applications. Additionally, its system and power on reset (SPOR) controller makes it suitable for use in medium-power systems that require reliable power supply monitoring and accurate power regulation.
