NCP4371AAEDR2G

Overview

The NCP4371AAEDR2G is a Qualcomm Quick Charge 3.0 High Voltage Dynamic Power Contract (HVDCP) controller manufactured by onsemi. It operates within a supply voltage range up to 28 V and supports an operating temperature range from -40 °C to +125 °C. The device draws a typical operating supply current of 300 µA. It is housed in an 8-SOIC package with a width of 3.90 mm. This component facilitates fast charging protocols for compatible mobile devices.

Feature Summary

• Supports Qualcomm Quick Charge 3.0 HVDCP protocol
• Wide operating temperature range for automotive and industrial use
• Low quiescent current consumption
• Integrated dynamic power contract negotiation

Applications

• Mobile phone fast chargers
• Tablet power adapters
• Consumer electronics charging docks
• Portable battery packs with QC 3.0 support

Procurement Notes

Verify the exact suffix 'AAEDR2G' against the official onsemi datasheet to ensure correct packaging and tape/reel specifications. Confirm RoHS compliance status as indicated in the latest revision. Check for obsolete status notifications, as some sources indicate this specific variant may be discontinued or limited in availability. Always reference the manufacturer's final documentation for ordering codes.

Selection Notes

Select this component when designing systems requiring native Qualcomm Quick Charge 3.0 compatibility. Ensure the input voltage capability meets the 28 V maximum requirement. Consider the 8-SOIC package constraints for PCB layout. Verify thermal management requirements given the +125 °C maximum junction temperature rating. Compare against newer onsemi alternatives if long-term supply assurance is critical.

Part Context

This part belongs to the NCP4371 family of HVDCP controllers designed for high-efficiency charging applications. It integrates the necessary logic to negotiate voltage levels between the charger and the device. The series is optimized for consumer electronics where fast charging standards are mandatory. It replaces older proprietary charging solutions with standardized QC 3.0 implementation.

Replacement Considerations

Check for direct pin-to-pin replacements within the NCP4371 family, such as NCP4371ACCDR2G, ensuring functional equivalence. Verify if newer onsemi models offer improved efficiency or updated packaging. Confirm that any substitute maintains full QC 3.0 certification requirements.
