Disadvantages: - Limited input voltage range (2.5V to 18V) - Not suitable for high-power applications

Working Principles

The TPS2400DBVR works by continuously monitoring the input voltage. When the voltage exceeds the set overvoltage threshold, the output is disabled to protect the system from potential damage. Similarly, if the voltage falls below the set undervoltage threshold, the output is also disabled to prevent improper operation. The adjustable thresholds allow flexibility in adapting the IC to different voltage requirements.

Application Field Plans

The TPS2400DBVR is commonly used in various electronic systems that require reliable overvoltage and undervoltage protection. Some specific application fields include:

1. Automotive Electronics: Protecting sensitive automotive components from voltage fluctuations.
