Key Featrues
Overvoltage Protection with External MOSFET Sizing: The device enables users to select and size external n-channel MOSFETs, providing flexibility in designing overvoltage protection circuits tailored to specific power requirements. This customization improves efficiency and ensures optimal performance in diverse use cases.
Internal Charge-Pump Circuit: The integrated charge-pump ensures proper gate-to-source voltage enhancement for external MOSFETs, resulting in low RDS(ON) performance. This reduces power losses and improves overall system efficiency, particularly in high-current applications.
Adjustable Overvoltage Threshold: The adjustable overvoltage threshold allows precise control over the protection level, enabling the device to be fine-tuned for specific application needs. This feature enhances system safety and reliability by preventing damage from voltage spikes or transients.
Thermal-Shutdown Protection: The built-in thermal-shutdown feature safeguards the device and connected components from overheating, ensuring long-term reliability and preventing failure in high-temperature environments. This is particularly beneficial in industrial and automotive applications where thermal stress is common.
