Key Featrues
Overvoltage Protection Up to +28V: This feature safeguards low-voltage systems by automatically disconnecting the load when the input voltage exceeds +28V, preventing potential damage to sensitive components and enhancing system reliability in high-voltage environments.
Reverse Polarity Protection Down to -28V: The device protects against negative voltage inputs as low as -28V, ensuring the system remains operational even in cases of incorrect power supply connections, thus improving robustness and safety.
Internal Charge Pump: The integrated charge pump eliminates the need for external capacitors, simplifying the design and reducing component count, which enhances overall system efficiency and reduces board space requirements.
Preset Overvoltage Trip Levels (7.4V, 6.35V, 5.8V, 4.65V): Multiple preset trip levels allow for precise overvoltage protection tailored to specific applications, ensuring optimal performance across a variety of use cases.
Overvoltage Fault FLAG Indicator: This feature provides a clear signal when an overvoltage fault occurs, enabling quick diagnosis and response to potential issues, thereby improving system maintenance and uptime.
