NCV8415DTRKG

Overview

The NCV8415DTRKG is a self-protected low-side driver manufactured by onsemi, designed for automotive and industrial applications. It features an N-channel output capable of delivering up to 7A with a typical on-resistance of 80 milliohms. The device supports a load voltage of 42V and operates within a junction temperature range of -40°C to 150°C. Packaged in a DPAK (TO-252-3) surface-mount housing, it includes integrated protection mechanisms such as overcurrent, overtemperature, and overvoltage safeguards. The component is AEC-Q101 qualified and RoHS compliant.

Feature Summary

• Integrated short-circuit protection utilizing surge current management
• Delta thermal shutdown with automatic restart capability
• Built-in drain-to-gate clamp for overvoltage protection and sensing
• Fault indication provided via the gate pin

Applications

• Switching drivers for capacitive, resistive, or inductive loads
• Replacement for electromechanical relays
• Replacement for discrete circuit solutions

Procurement Notes

Verify that the specific part number suffix matches the required tape-and-reel configuration for automated assembly lines. Confirm that the AEC-Q101 Grade 1 qualification aligns with your vehicle's reliability standards. Ensure the DPAK package footprint corresponds to your PCB layout constraints. Check for any recent PCN updates regarding material composition or manufacturing site changes before finalizing procurement orders.

Selection Notes

Select this component when a single-channel low-side switch with robust fault protection is required. It is suitable for replacing mechanical relays in space-constrained designs. Consider the 7A current rating and 80 milliohm resistance for thermal management calculations. Verify compatibility with logic-level inputs if analog driving capabilities are needed. Ensure the operating temperature range meets the environmental demands of the target application.

Part Context

This device belongs to onsemi’s portfolio of self-protected low-side drivers, specifically engineered for harsh automotive environments. The NCV prefix indicates compliance with unique address and control change requirements for automotive applications. It integrates smart FET technology to simplify system design while providing essential diagnostic features like fault signaling through the gate terminal.

Replacement Considerations

Direct substitutes within the same family include the NCV8415 without the TRKG suffix for different packaging options. Cross-reference with other onsemi low-side drivers if higher channel counts or different voltage ratings are required. Ensure any replacement maintains the same DPAK footprint and electrical characteristics to avoid redesign efforts.
