RAA489101ARGNP#HA0

Overview

The RAA489101ARGNP#HA0 is a buck-boost battery charger IC designed for mobile applications. It supports lithium-ion and lithium-polymer batteries with 2 to 4 cells. The device operates within a supply voltage range of 3.9 V to 23.4 V and delivers an output voltage between 3.9 V and 18.305 V. It features a 32-WFQFN exposed pad package (4x4 mm) and includes integrated USB Type-C compliance. The component supports programmable charging current, voltage, and timer settings.

Feature Summary

• Integrated USB Type-C Port Controller Interface (TCPCi) for protocol handling
• Buck-boost topology supporting wide input voltage ranges
• Programmable charging parameters including current, voltage, and timer

Applications

• Mobile device battery charging systems
• Lithium-ion polymer battery management
• USB Type-C powered portable electronics

Procurement Notes

Verify the specific suffix 'ARGNP#HA0' against the manufacturer's official datasheet to confirm pinout and electrical characteristics. Ensure compatibility with the target PCB footprint, specifically the 32-TQFN (4x4) package dimensions. Confirm RoHS3 compliance status if required by regional regulations before finalizing procurement orders.

Selection Notes

Select this component when a buck-boost architecture is required to handle varying input voltages relative to battery levels. It is suitable for designs requiring integrated USB Type-C control without external controllers. Verify that the 2-to-4 cell battery configuration matches the system requirements and that the 32-WFQFN package fits the thermal and spatial constraints of the application.

Part Context

This part belongs to the Renesas RAA489101 series of battery chargers. The series focuses on mobile applications with integrated power path management. The RAA489101ARGNP#HA0 variant specifically denotes the A-grade silicon revision housed in the GNP package with the HA0 ordering suffix, distinguishing it from other revisions or packaging options within the same functional family.

Replacement Considerations

Check the RAA489101A3GNP#HA0 for potential pin-compatible alternatives within the same series. Verify that any substitute maintains the 32-TQFN form factor and supports the required 2-to-4 cell configuration. Cross-reference the TCPCi integration requirements to ensure equivalent USB Type-C functionality.
