NCV887000D1R2G

Overview

The NCV887000D1R2G is an automotive-grade, non-synchronous boost DC-DC switching controller manufactured by onsemi. Designed for high-reliability applications, it operates within a supply voltage range of 2V to 40V and supports a fixed switching frequency of 170 kHz. The device features a maximum duty cycle of 90% and delivers an output current capability of 800 mA with a regulated output voltage of 10.5 V. It is qualified under AEC-Q100 standards and functions reliably across an extended junction temperature range from -40°C to +150°C.

Feature Summary

• Automotive-grade reliability certified to AEC-Q100 standards for harsh environment operation
• Integrated current limit protection to safeguard against overload conditions
• Fixed 170 kHz switching frequency enables compact external component sizing
• Wide input voltage range supports direct battery connection in vehicle systems

Applications

• Automotive start-stop systems requiring robust power management
• Boost conversion for LED lighting circuits in automotive interiors or exteriors
• General automotive electronics powering low-voltage loads from higher battery potentials
• Industrial control modules requiring wide input voltage tolerance

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and tape/reel specifications. Confirm AEC-Q100 qualification status if strict automotive compliance is required. Check for recent Product Change Notifications (PCN) regarding manufacturing site changes or material updates. Ensure compatibility with existing PCB footprint designs using the SOIC-8 package dimensions.

Selection Notes

Select this controller when a non-synchronous topology is sufficient for efficiency requirements. Consider the 170 kHz frequency for balancing EMI performance and passive component size. Evaluate thermal dissipation capabilities given the 800 mA output current in the SOIC-8 package. Verify that the 10.5 V output voltage aligns with downstream load requirements without additional regulation.

Part Context

This component belongs to the NCV887x series of automotive boost controllers from onsemi. It shares functional similarities with parts like the NCV8871 and NCV8873 but may differ in specific electrical parameters or feature sets. The series is designed to meet rigorous automotive quality standards while providing cost-effective power management solutions for various vehicle subsystems.

Replacement Considerations

Direct substitutes include NCV887100D1R2G and NCV887300D1R2G. Verify pinout compatibility and specific electrical parameter differences before substitution. Consult official datasheets for detailed comparison of operating temperatures and current limits.
