Supports smart battery chemistries with configurable cell counts from 2 to 7
Provides programmable charging parameters including current, voltage, and timer settings
Includes hardware fault protection against overvoltage and undervoltage conditions

Applications

Smart battery charger systems
Portable electronic devices requiring USB interface charging
Battery management solutions for multi-cell packs

Procurement Notes

Verify the specific suffix 'MA0' against official Renesas documentation, as standard listings often reference 'AA0' or 'HA0' variants which may differ in packaging or temperature ratings. Confirm availability through authorized distributors, noting that standard delivery periods are typically around 24 weeks. Ensure the selected part number matches the required operating temperature range and package type for the target design.

Selection Notes

Select this component when a buck-boost architecture is required for battery charging with a USB interface. Consider the 32-TQFN package constraints and the -10°C to 125°C operating range. Verify compatibility with the specific smart battery protocol and ensure the 6A maximum charge current meets system requirements. Check for alternative suffixes if different packaging options like tape-and-reel are needed.

Part Context

This part belongs to the RAA489118 series of battery chargers from Renesas Electronics Corporation. The series focuses on smart battery charging solutions with integrated power stages. Other variants in the family may offer different packaging styles or extended temperature ranges, but share the core buck-boost charging functionality and USB interface capabilities.
