NCV887711D1R2G

Overview

The NCV887711D1R2G is an automotive-grade non-synchronous boost controller designed for start-stop applications. It operates within a supply voltage range of 2 V to 40 V, supporting 45 V load dump conditions. The device utilizes peak current mode control with internal slope compensation and features factory-programmable automatic enable below the wake-up threshold. It includes cycle-by-cycle current limiting, hiccup-mode overcurrent protection, and thermal shutdown. The component is housed in an 8-SOIC package and is qualified to AEC-Q100 standards.

Feature Summary

• Automotive-grade non-synchronous boost controller ensuring regulated voltage during battery voltage sags
• Peak current mode control with internal slope compensation for stable operation
• Factory programmable automatic enable function triggered below wake-up threshold voltage
• Comprehensive protection including cycle-by-cycle current limit, hiccup-mode OCP, and thermal shutdown

Applications

• Start-stop vehicle systems requiring regulated voltage through cranking
• Infotainment and navigation power supplies during engine pauses
• Essential electronic systems needing seamless power transitions
• Applications requiring low quiescent current sleep mode operation

Procurement Notes

Verify the specific suffix D1R2G against official onsemi documentation to confirm factory-programmed output voltage settings and packaging configuration. Ensure compatibility with AEC-Q100 requirements for your target automotive application. Cross-reference the datasheet revision date to validate feature availability and electrical specifications before finalizing procurement.

Selection Notes

Select this component when designing systems that require automatic voltage boosting during low-battery conditions typical of start-stop vehicles. The fixed factory-programmed parameters suit designs where output voltage does not need external adjustment. Consider the 8-SOIC package constraints and thermal management capabilities relative to the expected load current and ambient operating temperatures.

Part Context

This part belongs to the NCV8877 family of automotive-grade non-synchronous boost controllers. The family is engineered to maintain power supply integrity for critical electronics during engine start-stop cycles. These controllers are specifically optimized for automotive environments, offering robust performance under extreme temperature variations and electrical noise conditions common in vehicle power trains.

Replacement Considerations

NCV887701D1R2G and NCV887720D1R2G are alternative variants within the same NCV8877 family. Verify if the factory-programmed output voltage or specific enable thresholds of these substitutes match the design requirements before substitution.
