NCV8405DTDRKG

Overview

The NCV8405DTDRKG is a self-protected low-side driver manufactured by onsemi, designed for robust power distribution in automotive and industrial environments. It features a single output with a maximum continuous current limit of 13 A and a typical on-resistance of 25 mΩ. The device operates within a supply voltage range up to 40 V and supports an input voltage up to 60 V. It includes integrated fault protection mechanisms such as over-temperature shutdown, over-voltage protection, and short-circuit limiting with auto-restart functionality. The component is qualified to AEC-Q100 standards and is housed in a DPAK-3 (TO-252-3) surface-mount package, ensuring reliable performance across an operating temperature range from -40°C to +150°C.

Feature Summary

• Integrated self-protection against over-temperature, over-voltage, and short-circuit conditions
• Auto-restart capability following fault events to maintain system availability
• AEC-Q100 qualification for automotive reliability requirements
• High current handling capacity suitable for heavy-load switching applications

Applications

• Automotive lighting systems requiring high-current switching
• Industrial motor control and relay driving
• Power distribution units in harsh environment electronics
• Heavy-duty solenoid and actuator drivers

Procurement Notes

Verify the specific suffix 'DTDRKG' against official onsemi documentation to confirm pinout and thermal characteristics, as variations exist within the NCV8405 family. Ensure compatibility with your PCB footprint for the DPAK-3 package. Confirm that the 13 A current rating aligns with your thermal management design, as dissipation depends heavily on ambient temperature and board copper area. Check for any recent product change notices or lifecycle status updates directly from the manufacturer before finalizing procurement.

Selection Notes

Select this component when a single-channel, high-current low-side switch with built-in fault protection is required. It is suitable for applications needing 13 A continuous load handling where space constraints favor a DPAK-3 package over larger through-hole options. Consider the 25 mΩ on-resistance for efficiency calculations. Compare with NCV8405BDTRKG if a different current rating or package variant is needed, but verify electrical specifications match the application's voltage and current demands precisely.

Part Context

The NCV8405 series comprises self-protected low-side drivers intended for demanding automotive and industrial loads. These devices integrate MOSFET technology with control logic to provide simplified switching solutions. The DTDRKG variant specifically denotes the DPAK-3 package configuration. This family addresses the need for compact, reliable power distribution components that can withstand electrical stress and thermal cycling common in vehicle and machinery environments.

Replacement Considerations

NCV8405BDTRKG is a related part in the same family; verify if its current rating and package suitability meet your specific design requirements before substitution.
