RAA489110A3GNP#HA0

Overview

The RAA489110A3GNP#HA0 is a buck-boost battery charger IC designed for general applications. It supports 2 to 7 series-connected cells with a maximum battery pack voltage of 30V and a maximum charging current of 6A. The device features a USB interface and operates within a supply voltage range up to 30V. It is housed in a 32-WFQFN exposed pad package (32-TQFN 4x4) and supports surface mount installation. The component offers programmable charge current, timer, and voltage settings, along with over-voltage and under-voltage fault protection.

Feature Summary

Integrates buck-boost topology for wide input voltage compatibility
Supports smart battery communication via USB interface
Provides programmable constant-current charging parameters
Includes built-in over-voltage and under-voltage fault protection

Applications

General purpose battery charging systems
Portable electronic devices requiring USB connectivity
Multi-cell lithium-ion battery packs

Procurement Notes

Verify the specific suffix 'HA0' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the 32-TQFN package dimensions align with your PCB footprint. Confirm RoHS3 compliance status if required by your assembly process. Check for any recent product change notifications that may affect lead times or material composition.

Selection Notes

Select this component when a buck-boost architecture is necessary to handle input voltages both above and below the battery pack voltage. The integrated USB interface simplifies system design for devices requiring direct host connection. Consider the 6A maximum current capability and the support for up to 7 series cells to ensure adequate power delivery for the target application.

Part Context

This part belongs to the Renesas RAA4891xx series of intelligent battery chargers. These ICs are designed to provide flexible charging solutions for multi-cell lithium-based batteries. The series typically integrates power switches and control logic to simplify board space and reduce component count compared to discrete solutions.
