NCV8405BDTRKG

Overview

The NCV8405BDTRKG is a self-protected low-side power switch IC manufactured by onsemi, designed for automotive and industrial applications. It features an N-channel MOSFET with a maximum load voltage of 42V and a continuous output current of 6A. The device includes integrated protection mechanisms such as fixed current limiting, overtemperature shutdown, and overvoltage clamp. It operates within a junction temperature range of -40°C to 150°C and is qualified under AEC-Q100 standards. The component is housed in a DPAK (TO-252-3) surface-mount package.

Feature Summary

• Integrated self-protection against overcurrent, overtemperature, and overvoltage conditions
• Automotive-grade reliability certified to AEC-Q100 standards
• Low-side switching configuration with non-inverting input interface

Applications

• High-side or low-side load switching in automotive body electronics
• Power distribution in industrial control systems
• Relay and solenoid driver circuits requiring fault protection

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance and halogen-free status per manufacturer documentation. Confirm the package variant matches the required thermal performance for your PCB layout. Ensure the ordering part number aligns with the tape-and-reel quantity specified in the official datasheet to avoid packaging discrepancies during assembly.

Selection Notes

Select this component when a single-chip solution for low-side switching with built-in fault protection is required. It serves as a direct replacement for discrete MOSFETs plus external protection circuitry, reducing board space and design complexity. Consider the 6A current rating and 42V voltage limit to ensure compatibility with the target load specifications and system voltage levels.

Part Context

This part belongs to the NCV8405A/B family of self-protected low-side smart discrete devices from onsemi. These components are engineered to simplify power management in harsh environments by integrating the driver, switch, and protection logic into a single package. The NCV prefix denotes automotive-grade qualification, distinguishing it from commercial variants.

Replacement Considerations

Direct substitutes include the NCV8405ADTRKG, which shares similar functionality but may differ in specific electrical parameters or packaging revisions. Verify pinout compatibility and thermal characteristics before substitution. Other members of the NCV8405 series should be evaluated based on current and voltage ratings.
