Overview
The onsemi NCV8402DDR2G is a low-side smart power switch featuring an N-channel MOSFET in an 8-pin SOIC package. It supports a load voltage up to 42V and delivers a continuous output current of 2A with a typical on-resistance of 165 milliohms. The device integrates comprehensive protection mechanisms including overcurrent, overtemperature, and overvoltage fault detection with auto-restart functionality. Certified to AEC-Q100 standards, it operates within a junction temperature range of -40°C to 150°C, ensuring reliability in automotive environments.
Feature Summary
- Integrates self-protected low-side switching with automatic fault recovery
- Provides robust overcurrent, overtemperature, and overvoltage protection
- Features high thermal stability for demanding automotive applications
Applications
- Automotive lighting control systems
- Solenoid and relay driver circuits
- General purpose load switching in vehicle ECUs
Procurement Notes
Verify the specific suffix DDR2G against official datasheets to confirm pinout and packaging dimensions. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm AEC-Q100 qualification status matches project specifications. Validate that the 42V rating aligns with system transient voltage levels.
Selection Notes
Select this component for applications requiring integrated protection in a compact surface-mount package. The 165 milliohm on-resistance offers efficient power handling for 2A loads. Consider the SOIC-8 footprint for ease of assembly. Verify that the low-side configuration suits the circuit topology compared to high-side alternatives.
Part Context
Part of the NCV8402 family of smart power switches designed for automotive durability. This series emphasizes reliability through built-in diagnostic features. The NCV prefix indicates automotive-grade qualification. The device simplifies design by combining power switching and protection in a single IC.
Replacement Considerations
Check NCV8402ADDR2G for SOIC-8 variants. Verify NCV8402ASTT1G for SOT-223 packaging options. Ensure substitute parts maintain identical protection thresholds and current ratings.
