PMIC - Supervisors is an important type of power management ICs (PMICs), which helps electronic systems control and balance their power supplies. The X5168S8T1 is one of the most popular supervisors and is used to monitor and control system voltages. Understanding its application fields and working principles will help you choose the right supervisor for your system.

Application Fields

The X5168S8T1 Supervisors are commonly seen in systems such as industrial controllers, consumer electronics and networking gear. These supervisors are usually present on board-level or PC board level, which helps to regulate power supplies, resulting in improved embedded system performance, especially in areas such as power sequencing.

The X5168S8T1 supervisors have multiple features which make them suitable for these applications. For example, these supervisors have an adjustable over-temperature protection range, supporting up to four adjustable voltage thresholds. They also have an integrated Power-On Reset generator and a Power-Good output.

The X5168S8T1 supervisors can also be used to provide system level protection. They can monitor voltage and current levels, allowing the system to reset itself if a fault is present. This can help to reduce system downtime as the supervisors are able to quickly detect an issue and reset the system, avoiding potential system damage.

Working Principles

The X5168S8T1 supervisors are based on a voltage-monitoring circuit that allows the voltage threshold to be adjusted. It has a base voltage of 2.5V, which can be adjusted to trigger the reset (RST) in either rising or falling mode.

The supervisors have a brown-out protection feature which monitors the input voltage and will trigger the reset if it falls below a preset level. This is important as it can prevent malfunctions if the input voltage drops below the necessary operating level.

The X5168S8T1 supervisors also have an over-voltage protection feature, which can be used to protect sensitive components from excessive current. The device monitors the input voltage and will trigger the RST if the voltage exceeds a preset level.

Finally, the X5168S8T1 supervisors have a power-good (PG) output, which provides an indication of the regulated output voltage. It helps the system controller to determine whether there is sufficient voltage for it to continue to run.

Conclusion

The X5168S8T1 Supervisors are a type of power management IC that are ideal for embedded system applications. They are able to monitor and control system voltages and provide system level protection through features such as brown-out and over-voltage protection. The device also features a power-good output, which provides an indication of regulated output voltages.

With its wide range of features, the X5168S8T1 is an ideal choice for systems such as industrial controllers, consumer electronics and networking gear. Understanding the application fields and working principles of this supervisor can help you choose the right device for your system.
