PMIC - Supervisors are a type of integrated circuit specialized in voltage level or signal monitoring and protection to keep any embedded system stable and operational. Their main job is to monitor power supply levels and other key signals in the embedded system, and emit a reset signal in case of any irregularities. X5168S8I-4.5AT1 is one such product in the Power Manageable Intelligent Controller (PMIC)Supervisors series. This article will look at its application field and working principle.

Application Field

X5168S8I-4.5AT1 is an Integrated Voltage Supervisor with low power operation and comprehensive options. It is widely used in lithium-ion battery-, automotive- and industrial-grade applications, especially for system power resetting for single-cell +5V systems. Its low current operations, adjustable reset threshold and reset output enable it to simplify circuit design and improve system reliability. Furthermore, its wide operating temperature (–40 °C to +125 °C) makes it applicable in extreme environments.

Working Principle

The working principle of X5168S8I-4.5AT1 is quite simple. It constantly monitors the power supply, reverse current and other key signals and compares the monitored level with a reference voltage or threshold. In case of any irregularities, such as power supply drops, reverse current, over- or under-voltage and over- or under-current, it will emit a RESET/OFF signal to push the system back to normal. This reset signal can be issued either in the form of an interrupt line or reset pulse, depending on user preference.

In addition to monitoring power and key signals, X5168S8I-4.5AT1 also integrates a Reset Timer for automatic reset and a Power-on-Reset generation, both of which guarantee reliable operation in emergencies. It also provides pins for power switch control, allowing users to switch power supply without resetting the system, thus providing easy but highly efficient control.

Conclusion

X5168S8I-4.5AT1 is a highly effective PMIC Supervisor applicable in various fields and environments. Its low power operation, adjustable reset threshold and various reset output and control functions ensure that all systems can operate stably and reliably with minimal interference. As a result, it is increasingly popular for lithium-ion battery-, automotive- and industrial-grade applications, as well as for single-cell +5V systems.
