NCV8405ASTT1G

Overview

The NCV8405ASTT1G is a self-protected low-side power distribution switch manufactured by onsemi. It features an N-channel output with a maximum continuous current of 6 A and a typical on-resistance of 90 mOhms, with a maximum rating of 210 mOhms. The device supports a load voltage up to 40 V and operates within a temperature range of -40°C to +150°C TJ. It includes fixed current limiting, overtemperature protection, and overvoltage fault protection with auto-restart capabilities. Packaged in a SOT-223 (TO-261) surface-mount case, it is qualified under the AEC-Q100 automotive standard.

Feature Summary

Integrates self-protection mechanisms including fixed current limit, overtemperature shutdown, and overvoltage handling with automatic restart functionality.
Provides a single low-side N-channel output configuration for direct load switching applications.
Designed for automotive environments with qualification meeting AEC-Q100 reliability standards.

Applications

Automotive body electronics load distribution
General purpose power switching in vehicle networks
Protection of low-current automotive peripherals

Procurement Notes

Verify the specific suffix 'TT1G' against the official onsemi datasheet to confirm package type and tape/reel specifications. Ensure the AEC-Q100 qualification status aligns with your system's automotive grade requirements. Cross-reference the pinout diagram for the SOT-223 package to prevent layout errors during PCB design. Confirm RoHS compliance details if environmental regulations are critical for your target market.

Selection Notes

Select this component when a single low-side switch with 6 A capacity and integrated fault protection is required. Compare the 90 mOhms typical on-resistance against thermal dissipation needs in the SOT-223 package. Consider the 40 V load voltage limit relative to the system bus voltage. Evaluate the auto-restart feature suitability for transient fault conditions versus latching protection alternatives.

Part Context

This part belongs to the NCV8405A series of self-protected power switches from onsemi. It is designed specifically for automotive applications requiring robust load management. The series offers various current ratings and voltage levels within the same family, allowing designers to standardize on a consistent interface and protection architecture across different vehicle subsystems.
