NCV8401DTRKG

Overview

The NCV8401DTRKG is a self-protected low-side driver manufactured by onsemi, designed for switching resistive, inductive, and capacitive loads. It operates within a supply voltage range of 5 V to 34 V and features an integrated N-channel MOSFET with a typical on-resistance (RDS(on)) of 23 mΩ. The device includes built-in current limiting, thermal shutdown with automatic restart, and overvoltage protection. It is housed in a DPAK-3 (TO-252-3) surface-mount package and supports operation temperatures from -40°C to +150°C TJ. The component is AEC-Q100 qualified for automotive applications.

Procurement Notes

Verify the specific suffix 'DTRKG' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the procurement source provides valid traceability documentation. Confirm that the component meets the required AEC-Q100 qualification standards for your specific application environment before finalizing orders.

Selection Notes

Select this component when a low-side driver with integrated protection is required for loads up to 34 V. The low RDS(on) value makes it suitable for applications demanding high efficiency. Consider the DPAK-3 package for its thermal performance and mounting convenience. Verify that the input logic levels are compatible with the driving circuitry.

Part Context
