BQ24770RUYR

Battery Management Overview

The BQ24770RUYR is a high-efficiency, synchronous NVDC-1 battery charge controller manufactured by Texas Instruments. It supports 1 to 4 series cells and utilizes SMBus communication for system integration. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a 28-WQFN (4x4 mm) package with an exposed pad. It features an input voltage range of 4.5 V to 24 V and delivers a maximum output current of 8 A. The component is RoHS3 compliant and classified under ECCN EAR99.

Battery Management Feature Summary

• Integrates power path management to regulate the system at battery voltage without dropping below it.
• Includes a system power monitor and processor thermal indicator for enhanced safety and control.
• Supports multi-chemistry batteries with low external component count for space-constrained designs.

Battery Management Applications

• Portable computers and notebooks
• Industrial equipment requiring NVDC architecture
• Medical devices with strict power management needs

Battery Management Procurement Notes

Verify the specific suffix RUYR against the official datasheet to confirm the 28-WQFN package and tape & reel packaging configuration. Ensure compatibility with the required SMBus interface and operating temperature range (-40°C to +85°C). Confirm that the 8 A output current capability aligns with the target application's power requirements before finalizing procurement.

Battery Management Selection Notes

Select this component when an NVDC-1 topology is required to maintain system operation during adapter removal. It is suitable for applications needing precise battery charging profiles for multiple cell counts (1S to 4S). Consider the 28-WQFN footprint for PCB layout constraints and verify SMBus master compatibility for system monitoring functions.

Battery Management Part Context

This part belongs to the BQ2477x family of battery charge controllers from Texas Instruments. It shares architectural similarities with the BQ24773 but differs in specific feature sets and pin configurations. The family targets high-performance portable electronics requiring efficient power path management and advanced battery monitoring capabilities.

Battery Management Replacement Considerations

The BQ24773RUYT is a related member of the same family. Verify functional equivalence regarding NVDC implementation and SMBus registers before substitution. Pin-to-pin compatibility must be confirmed via respective datasheets as feature sets may vary between variants.
