BQ25628ERYKR

Battery Chargers Overview

The BQ25628ERYKR is a single-cell lithium-ion/polymer battery charger IC from Texas Instruments, housed in an 18-WQFN-HR (3x2.5) package. It features a maximum input voltage of 18V and supports up to 2A charging current. The device utilizes an I2C interface for configuration and includes programmable charge current, timer, and voltage settings. Operating temperature range is -40°C to 85°C.

Battery Chargers Feature Summary

• Integrates power path management with internal MOSFETs for seamless system power switching between input source and battery.
• Supports narrow VDC power path management to maintain system voltage above the minimum configurable threshold.
• Includes comprehensive safety features such as thermal regulation, input overvoltage protection, and battery temperature monitoring via NTC thermistor.

Battery Chargers Applications

• Portable consumer electronics requiring efficient single-cell battery charging
• IoT devices needing low quiescent current and compact footprint
• Industrial data acquisition nodes requiring reliable power path management

Battery Chargers Procurement Notes

Verify the ERYKR suffix corresponds to the specific reel quantity and tape configuration required for your assembly line. Confirm that the 18-WQFN-HR package dimensions match your PCB land pattern. Ensure I2C address configuration aligns with your system bus architecture before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a highly integrated solution for single-cell Li-ion/Li-polymer batteries is needed. It is suitable for designs prioritizing small board space due to its 3x2.5mm package. Choose if your application requires flexible input sources including USB ports and high-voltage adapters up to 18V.

Battery Chargers Part Context

This part belongs to the BQ2562x family of battery chargers designed for portable applications. It shares architectural similarities with the BQ25629 but lacks specific pins like TS_BIAS found in other variants. The family emphasizes efficiency and safety through integrated synchronous buck conversion and robust fault protection mechanisms.

Battery Chargers Replacement Considerations

BQ25629RYKR is a documented substitute within the same family, offering similar functionality with additional pin configurations for thermistor biasing.
