2U3809L30QDBVRG4Q1 can be used in a variety of markets and applications. It is used for multiplexer control, for data processing and for lighting systems. It can be used for automotive, industrial, and military applications. This part provides a high level of reliability and robust performance. It can be used in particular in the automotive industry, where power protection and high temperature performance requirements are of particular importance. Also, the offering is suitable for medical devices, industrial systems and consumer electronics.

Working Principle

2U3809L30QDBVRG4Q1 is an integrated circuit that integrates the overvoltage protection, overcurrent protection, and automatic restart functions which help protect microcomputer systems. It also adds an auto-restart function to assist recovery from overvoltage or overcurrent conditions, thus providing greater system reliability. This part is designed to detect input voltage fluctuations or overcurrent, and provides reset signals to the system to enter a safe operating condition if either is detected. If the voltage or current remains outside the range for longer than the timeout period, then the device will reset the system. Finally, the part can be configured for automatic reset if the condition persists, or for manual reset if the device operator must intervene.

This part uses a dual-mode-level converter that maintains the reference level at the correct voltage, even when current and temperature variations occur. Also, there is a adjustable digital level-detection circuit which can detect different voltage levels. When unstable current or voltage is detected, the device immediately sends an acknowledge signal to the system indicating that the system should be reset. After resetting the system, the circuit will retain its last programmed settings, allowing the device to operate with less disruption.

Conclusion

2U3809L30QDBVRG4Q1 is a Power Management IC (PMIC) Supervisors that offers efficient and cost effective system protection, operating over the wide temperature range of -40 degrees to +85 degrees C. It is widely used for multiplexer control, for data processing and for lighting systems. The device is designed to detect input voltage fluctuations or overcurrent, and provides reset signals to the system to enter a safe operating condition if either is detected. The part also uses a dual-mode-level converter that maintains the reference level at the correct voltage, even when current and temperature variations occur.
