RAA489118ARGNP#HA0

Overview

The RAA489118ARGNP#HA0 is a smart battery charger IC from Renesas Electronics Corporation, designed for narrow voltage DC battery charging applications. It features a buck-boost topology and supports lithium-ion battery chemistries with up to 7 cells in series. The device integrates USB interface capabilities and offers programmable constant-current charging up to 6A. It operates within a supply voltage range of up to 30V and functions across an extended temperature range of -40°C to +105°C. Packaged in a 32-TQFN (4x4) format, it includes over-voltage and under-voltage fault protection mechanisms.

Feature Summary

• Integrates buck-boost converter topology for flexible input-output voltage handling
• Supports smart battery communication protocols via integrated USB interface
• Provides programmable charging parameters including current, voltage, and timer settings
• Includes hardware-level over-voltage and under-voltage fault protection

Applications

• Narrow voltage DC battery charging systems
• Smart battery management for multi-cell lithium-ion packs
• USB-powered portable electronic devices requiring intelligent charging

Procurement Notes

Verify the specific suffix 'A3' versus 'AR' against official Renesas documentation, as these denote distinct product variants within the RAA489118 family. Confirm package type matches the required 32-TQFN form factor. Ensure environmental compliance requirements align with RoHS3 standards. Check moisture sensitivity level (MSL 3) constraints for storage and handling procedures prior to assembly.

Selection Notes

Select this component when a buck-boost architecture is necessary to accommodate varying input voltages relative to the battery pack. Consider its integration of USB interfaces if direct host communication or power delivery negotiation is required. Evaluate the 6A maximum current capability against system load requirements. Verify that the 32-TQFN package fits the available PCB real estate and thermal dissipation needs.
