X4163S8

PMIC - Supervisors

The X4163S8 is a supervisor IC (integrated circuit) designed to provide multiple supply voltage-monitoring, watchdog timer, and reset function in a single chip. This product has been designed to keep power systems running properly and monitor user data and system operations, ensuring that the system is functioning efficiently and remains stable. The X4163S8 has a wide operating temperature range, low power consumption, and several features that make it advantageous over traditional supervisor solutions.

Application Field

The X4163S8 is an excellent choice for applications where a wide operating temperature range, low power consumption and adjustable reset thresholds are essential. It is suitable for a wide range of applications including restarts, infrared remote control systems, modems, and data communications applications. The X4163S8 provides effective reset monitoring and voltage surveillance for single and multiple-systems with its adjustable reset thresholds, watchdog timer and full reset delay control.

The X4163S8 also has the flexibility needed for commercial, medical, and military applications where reset detection and voltage monitoring are critical. It is widely used in computers, networking systems, medical equipment and other mission-critical systems to ensure its proper functioning.

Working Principle

The X4163S8 features a voltage-monitoring system, watchdog timer, reset functionality, and several other features. The IC includes two reset-kicks during Brown-Out or brownout Detects (BODs) and a power fail detect window. The X4163S8 has an adjustable reset threshold, full reset delay time, and minor cycle reset time.

The voltage-monitoring system monitors the supply voltage and will assert a reset if the voltage drops below the preset threshold. The watchdog timer ensures that the system remains active and restarts in case of a system failure. Additionally, the X4163S8 has an integrated reset function that requires a manual reset. The reset source can be controlled by an external pin or by the internal power fail detect window.

The X4163S8 also has additional features such as under-voltage lockout (UVLO) and open-drain output (ODO) which allow engineers to adjust the reset thresholds and increase the accuracy of their system. Additionally, the IC can be configured to support manual reset, watchdog and power fail detect modes.

Conclusion

The X4163S8 is an ideal IC for applications requiring multiple supply voltage monitoring, watchdog timer, and reset function. The IC has a wide operating temperature range, low power consumption, and many features that make it advantageous versus traditional supervisors. The adjustable reset thresholds, full reset delay time, and minor cycle reset time are all important features for commercial, military, and medical applications. The integrated reset and open-drain output functions make the X4163S8 a reliable and efficient solution for ensuring system stability and proper functionality.
