RAA489220AGNP#HA5

Battery Management Overview

The RAA489220AGNP#HA5 is a standalone battery protection IC designed for multi-cell lithium-ion and lithium-polymer packs. It supports 4 to 10 series cells with an operating supply voltage range of 6 V to 44 V. The device integrates low-side current sensing, a 3.3 V regulator output, and temperature monitoring. Protection features include over-current, over/under-voltage, short-circuit, and over-temperature detection. Communication is handled via I2C interface. It operates from -40°C to 85°C in a 32-QFN package.

Battery Management Feature Summary

• Integrated low-side current sensing for precise charge and discharge monitoring
• Comprehensive fault protection including over-current, over/under-voltage, short-circuit, and over-temperature
• Built-in 3.3 V regulator output and integrated temperature sensor
• Digital control and status reporting via I2C communication interface

Battery Management Applications

• Portable electronic devices requiring multi-cell battery management
• Power tools with lithium-ion battery packs
• Uninterruptible power supply (UPS) systems
• Medical equipment with rechargeable battery backups

Battery Management Procurement Notes

Verify the specific suffix HA5 against official Renesas documentation to confirm pinout and electrical characteristics. Ensure compatibility with your system's I2C address configuration. Check moisture sensitivity levels and reflow soldering profiles during assembly planning. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement.

Battery Management Selection Notes

Select this component when designing systems requiring protection for 4 to 10 series cells within a 44 V maximum supply limit. It is suitable for applications needing integrated current sensing without external shunt resistors. Consider the 32-QFN package constraints for PCB layout. Verify that the I2C interface meets your microcontroller's communication speed and addressing needs.

Battery Management Part Context

This part belongs to the RAA4892062 family of battery management solutions from Renesas Electronics. While other variants may support different cell counts or packages, this specific model focuses on mid-range cell configurations. It complements Renesas' broader portfolio of power management ICs for portable and industrial applications.

Battery Management Replacement Considerations

Direct substitutes are not explicitly confirmed in public datasheets. Evaluate alternative Renesas models within the RAA4892xx series for similar cell count support. Verify functional equivalence regarding protection thresholds and I2C compatibility before substitution.
