NCV8452STT3G

Overview

The NCV8452STT3G is a single-channel high-side power switch IC from onsemi, designed for load distribution applications. It operates within a supply voltage range of 5 V to 34 V and supports a maximum continuous output current of 500 mA with a current limit of 1 A. The device features a maximum on-resistance of 400 mOhms and includes protection against over-temperature conditions. It is qualified under the AEC-Q100 standard for automotive reliability. The component is housed in a compact SOT-223-4 surface-mount package and functions reliably across an extended temperature range from -40°C to +150°C.

Feature Summary

• Single-channel high-side driver architecture for direct load control
• Integrated thermal shutdown protection for fault management
• Automotive-grade qualification ensuring robust performance in harsh environments

Applications

• Automotive lighting systems
• Power distribution units in vehicle electronics
• General purpose load switching in automotive modules

Procurement Notes

Verify the specific suffix 'STT3G' to confirm the reel packaging configuration and tape-and-reel quantity. Ensure the procurement order explicitly references the AEC-Q100 qualification status if automotive compliance is required. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and traceability before finalizing orders.

Selection Notes

Select this component when a single-channel high-side switch with integrated thermal protection is required. The 500 mA output capability suits low-to-medium power loads. Verify that the system supply voltage remains within the 5 V to 34 V operational window. Consider the SOT-223-4 package constraints for thermal dissipation and PCB layout requirements during the design phase.

Part Context

This part belongs to the NCV8452 series of protected high-side switches. It is distinct from similar models like the NCV8450ASTT3G, which may offer different voltage ratings or current capabilities. The NCV8452 series is specifically engineered for automotive applications requiring reliable load switching with built-in safety features.

Replacement Considerations

Direct substitutes include other parts within the NCV8452 family, such as NCV8452STT1G, provided pinout and electrical specifications match exactly. Always verify functional equivalence and package compatibility before substitution.
